Here is the step-by-step solution to each word problem on the worksheet, explained clearly for Grade 2 level understanding.

Problem 1:
> If you run for 15 minutes, how long will it take to run for a half hour?
Explanation:
- We know that
1 half hour = 30 minutes.
- You have already run for
15 minutes.
- To find out how much longer you need to run to reach 30 minutes, subtract:
> 30 minutes – 15 minutes =
15 minutes
✔ Answer: 15 more minutes
---
Problem 2:
> If you read for 20 minutes and then skip for 10 minutes, how long have you been active for?
Explanation:
- “Active” means doing something — reading AND skipping both count.
- Add the two times together:
> 20 minutes + 10 minutes =
30 minutes
- 30 minutes is also called
half an hour.
✔ Answer: 30 minutes or 1/2 hour

Problem 3:
> If you walk for 45 minutes, how much longer do you need to walk to reach 1 hour?
Explanation:
-
1 hour = 60 minutes
- You’ve walked
45 minutes.
- Subtract to find the remaining time:
> 60 minutes – 45 minutes =
15 minutes
✔ Answer: 15 minutes

Problem 4:
> If you skip for 30 minutes and then run for 15 minutes, how long have you been active for?
Explanation:
- Both skipping and running are activities — so we add them.
> 30 minutes + 15 minutes =
45 minutes
- 45 minutes is also called
three-quarters of an hour (3/4 hour).
✔ Answer: 45 minutes or 3/4 hour

Problem 5:
> If it takes you 10 minutes to read a book, how long will it take to read 6 books?
Explanation:
- Each book takes
10 minutes.
- For 6 books: multiply
> 6 × 10 minutes =
60 minutes
- 60 minutes =
1 hour
✔ Answer: 1 hour
---
Problem 6:
> If you play outside for 20 minutes and then read for 15 minutes, how long have you been active for?
Explanation:
- Playing and reading are both activities — so we add the times.
> 20 minutes + 15 minutes =
35 minutes
⚠️ Note: The answer key at the bottom says “45 minutes or 3/4 hour”, which is
incorrect for this problem.
Let’s double-check:
- 20 + 15 =
35 minutes, not 45.
- 35 minutes is
not equal to 3/4 hour (which is 45 minutes).
✔ Correct Answer: 35 minutes
