Elapsed Time — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A Grade 4 trip leaves at 8:15 AM, drives 45 min, stops 30 min, drives 1 h 20 min — arrival time is 10:50 AM.
Grade 4 multi-step elapsed time adds each segment to the start time in order.
2. Liam starts homework at 4:10 PM, works 25 min, breaks 10 min, works 35 min in Grade 4 — finishes at 5:20 PM.
Grade 4 students sum every activity, including breaks, to find the final clock time.
3. A Grade 4 bus leaves at 11:30 AM, rides 50 min, lunch 40 min, walks 15 min — arrival is at 1:15 PM.
Grade 4 elapsed time across noon converts AM totals into PM clock times by counting past 12:00.
4. Mia bakes for 1 h 15 min and cools 25 min starting at 9:50 AM in Grade 4 — finishes at 11:30 AM.
Grade 4 students convert mixed hour-minute durations into total minutes before adding to the start time.
5. A Grade 4 game starts at 6:45 PM, plays 1 h 30 min, takes 20 min break, plays 45 min — ends at 9:20 PM.
Grade 4 multi-step problems require summing all durations before finding the final time on the clock.
6. From 7:00 AM to 11:30 AM the Grade 4 elapsed time is 4 hours 30 minutes.
Grade 4 elapsed time within AM uses simple hour subtraction plus the leftover minutes.
7. Aiden runs errands: 35 min, 20 min, 45 min — total elapsed time for Grade 4 is 100 minutes.
Grade 4 students total up multiple durations by simple addition before converting to hours and minutes.
8. If Grade 4 movie 1 lasts 95 min and movie 2 lasts 105 min, total elapsed time is 3 hours 20 minutes.
Grade 4 students add total minutes, then convert to hours and remaining minutes for a clean answer.
9. A Grade 4 task starts at 2:25 PM and ends at 4:10 PM, an elapsed time of 1 hour 45 minutes.
Grade 4 elapsed time within PM is solved by counting full hours plus leftover minutes.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Start 8:15 AM, drive 45 min, stop 30 min, drive 1 h 20 min — arrival
→ 10:50 AM
10:50 AM
Total minutes for 1 h 30 min + 45 min in Grade 4
→ 135 minutes
135 minutes
Start 11:30 AM, ride 50 min, lunch 40 min, walk 15 min — arrival
→ 1:15 PM
1:15 PM
Convert 200 minutes to hours and minutes
→ 3 hours 20 minutes
3 hours 20 minutes
Grade 4 multi-step elapsed time uses minute totals or step-by-step addition to land on the correct answer.
