Worksheet: Exercises 1 to 3
1 Simple Elapsed Time
Exercise 1
Sarah started reading at 3:45 PM and finished at 4:20 PM. How long did Sarah read?
Definition:

Elapsed time: The amount of time that passes between two events.

Time calculation method:
  1. Identify the start and end times
  2. Calculate hours first, then minutes
  3. If minutes in start time > minutes in end time, borrow an hour
  4. Combine hours and minutes for total elapsed time
Start Time
3:45 PM
End Time
4:20 PM
Step 1: Identify start and end times

Start: 3:45 PM, End: 4:20 PM

Step 2: Calculate hours and minutes separately

Hours: 4 - 3 = 1 hour

Minutes: 20 - 45 = ? Since 20 < 45, we need to borrow

Step 3: Borrow an hour to subtract minutes

Convert 1 hour to 60 minutes: 1 hour - 1 hour = 0 hours

Add to minutes: 20 + 60 = 80 minutes

Now subtract: 80 - 45 = 35 minutes

Step 4: Combine hours and minutes

Total time = 0 hours 35 minutes = 35 minutes

Sarah read for 35 minutes
Final answer:

Sarah read for 35 minutes

Applied rules:

• Elapsed time: End time - Start time

• Borrowing rule: When minutes in start > minutes in end, borrow 1 hour = 60 minutes

• Time conversion: 1 hour = 60 minutes

2 Time Conversion Problem
Exercise 2
A movie lasted 1 hour and 40 minutes. How many minutes long was the movie?
Definition:

Time conversion: Changing time from one unit to another (hours to minutes, etc.).

Hours
1
Minutes
40
Unit Conversion Factor Value
Hours to Minutes × 60 1 × 60 = 60 minutes
Additional Minutes No conversion needed 40 minutes
Step 1: Convert hours to minutes

1 hour = 1 × 60 = 60 minutes

Step 2: Add the additional minutes

60 minutes + 40 minutes = 100 minutes

Step 3: State the final answer

The movie lasted 100 minutes

The movie lasted 100 minutes
Final answer:

The movie lasted 100 minutes

Applied rules:

• Time conversion: 1 hour = 60 minutes

• Multiplication: Hours × 60 = minutes

• Addition: Total minutes = converted hours + original minutes

3 Start Time Calculation
Exercise 3
A soccer game lasted 75 minutes and ended at 5:00 PM. What time did the game start?
Definition:

Start time calculation: Finding the beginning time when given end time and duration.

End Time
5:00 PM
Duration
75 min
Step 1: Convert duration to hours and minutes

75 minutes = 1 hour and 15 minutes (since 75 ÷ 60 = 1 remainder 15)

Step 2: Subtract the duration from end time

Start time = End time - Duration

Start time = 5:00 PM - 1 hour 15 minutes

Step 3: Subtract hours first

5:00 PM - 1 hour = 4:00 PM

Step 4: Subtract the remaining minutes

4:00 PM - 15 minutes = 3:45 PM

Step 5: State the final answer

The game started at 3:45 PM

The game started at 3:45 PM
Final answer:

The game started at 3:45 PM

Applied rules:

• Start time: End time - Duration

• Time conversion: Convert total minutes to hours and minutes

• Subtraction: Subtract hours first, then minutes

  3. Execute: Perform calculations with attention to borrowing/adding
  4. Verify: Check if the answer makes sense in context
Tip 1: Draw a timeline to visualize the problem.
Tip 2: When minutes in start > minutes in end, always borrow 1 hour (60 minutes).
Tip 3: For multi-day problems, count full days first, then calculate partial days.
Tip 4: Always check if your answer is reasonable.
Common errors: Forgetting to borrow when minutes exceed, mixing up AM/PM, incorrect conversion factors.
Key facts: Remember basic time conversions: 60 seconds = 1 minute, 60 minutes = 1 hour, 24 hours = 1 day.
Time conversion formulas:

• Hours to minutes: multiply by 60

• Minutes to hours: divide by 60

• Days to hours: multiply by 24

• Hours to days: divide by 24

• Elapsed time: End time - Start time

Worksheet: Exercises 4 to 5
4 Time Addition Problem
Exercise 4
Tom practiced piano for 45 minutes on Monday and 30 minutes on Tuesday. How many minutes did he practice in total?
Definition:

Time addition: Adding multiple time durations together.

Monday
45 min
Tuesday
30 min
Step 1: Add the minutes together

45 minutes + 30 minutes = 75 minutes

Step 2: Convert to hours and minutes if needed

75 minutes = 1 hour and 15 minutes (since 75 ÷ 60 = 1 remainder 15)

Step 3: State the final answer

Tom practiced for 75 minutes total (or 1 hour 15 minutes)

Tom practiced for 75 minutes total
Final answer:

Tom practiced for 75 minutes total

Applied rules:

• Time addition: Add minutes together

• Conversion: When minutes ≥ 60, convert to hours

• Regrouping: Add converted hours to total hours

5 Time Subtraction with Borrowing
Exercise 5
A bus trip took 2 hours and 10 minutes. If the bus traveled for 1 hour and 45 minutes, how much longer was the rest of the trip?
Definition:

Time subtraction: Finding the difference between two time durations.

Total Trip
2:10
Traveled
1:45
Step 1: Set up the subtraction

Total trip - Traveled = Remaining time

2 hours 10 minutes - 1 hour 45 minutes = ?

Step 2: Subtract hours and minutes separately

Hours: 2 - 1 = 1 hour

Minutes: 10 - 45 = ? Since 10 < 45, we need to borrow

Step 3: Borrow an hour to subtract minutes

Convert 1 hour to 60 minutes: 1 hour - 1 hour = 0 hours

Add to minutes: 10 + 60 = 70 minutes

Now subtract: 70 - 45 = 25 minutes

Step 4: Combine hours and minutes

Remaining time = 0 hours 25 minutes = 25 minutes

The rest of the trip was 25 minutes long
Final answer:

The rest of the trip was 25 minutes long

Applied rules:

• Time subtraction: Total - Part = Remaining

• Borrowing rule: When minutes in minuend < subtrahend, borrow 1 hour = 60 minutes

• Regrouping: Add borrowed minutes to original minutes

Questions & Answers

Question: I'm confused about borrowing time. When do I need to borrow and how do I do it?

Answer: You need to borrow when you're subtracting time and the minutes in the first number are smaller than the minutes in the second number. For example, in 4:20 - 3:45, since 20 < 45, you need to borrow. Here's how:

  • Take 1 hour from the hours column (4 hours becomes 3 hours)
  • Add 60 minutes to the minutes column (20 minutes + 60 minutes = 80 minutes)
  • Now you have 3:80 - 3:45, which is easy to subtract: 0 hours and 35 minutes

Think of it like exchanging a $1 bill for 100 cents when you need to make change!

Question: My child struggles with time word problems. How can I help them understand better?

Answer: Here are effective strategies to help your child with time word problems:

  • Use a real analog clock to demonstrate time concepts
  • Create visual timelines showing start and end times
  • Practice with everyday activities: "How long until dinner?"
  • Break problems into smaller steps and practice each step separately
  • Encourage estimation before calculating exact answers
  • Use manipulatives like clock faces or time strips
  • Work through worksheets together, showing solution steps

Make it fun with games like "What time will it be in 30 minutes?" or "How many minutes until bedtime?" Consistent practice with visual aids will build confidence.

Question: How do I know if my worksheet answers are right when doing time problems?

Answer: Here are ways to check if your time problem answers are correct:

  • Estimate first: Think about if your answer makes sense
  • Add back: If you found elapsed time, add it back to the start time to see if you get the end time
  • Visual check: Draw a clock or timeline to see if your answer looks right
  • Reasonableness: Does the time seem realistic for the situation?
  • Alternative method: Try solving the problem a different way
  • Step verification: Go through each step of your solution
  • Worksheet review: Check your work after completing all problems

For example, if you calculated that a 1-hour movie lasted 60 minutes, that's correct because 1 × 60 = 60. Always verify your worksheet answers!
