Let’s solve each time calculation problem step by step.

Problem (1):

> Richa’s mom drops her off at the mall at 1:00 p.m. and tells her that she will pick Richa up in 17 hours and 25 minutes. What time will Richa’s mom pick her up?

Step-by-step solution:

Start time: 1:00 p.m.

Add 17 hours:

- 1:00 p.m. + 12 hours = 1:00 a.m. (next day)
- 1:00 a.m. + 5 hours = 6:00 a.m. (still next day)

Now add 25 minutes to 6:00 a.m. → 6:25 a.m.

✔ Answer: 6:25 a.m.

Problem (2):

> Karishma went outside at 9:46 p.m. and played 8 hours and 53 minutes before she came back inside. When did Karishma come back inside?

Step-by-step solution:

Start time: 9:46 p.m.

Add 8 hours:

- 9:46 p.m. + 8 hours = 5:46 a.m. (next day)

Now add 53 minutes:

- 5:46 a.m. + 53 minutes = ?

Break it down:
- 5:46 a.m. + 14 minutes = 6:00 a.m.
- 53 - 14 = 39 minutes left
- 6:00 a.m. + 39 minutes = 6:39 a.m.

✔ Answer: 6:39 a.m.

Problem (3):

> Karina wanted to break the world's record for standing on one foot. She started at 8:34 a.m. and fell over 23 hours and 34 minutes later. What time did she fall over?

Step-by-step solution:

Start time: 8:34 a.m.

Add 23 hours and 34 minutes

First, note that 24 hours would bring us back to the same time next day. So adding 23 hours and 34 minutes is almost a full day — just 26 minutes short of 24 hours.

So:

- 8:34 a.m. + 24 hours = 8:34 a.m. (next day)
- But we’re adding only 23 hours 34 minutes, so subtract 26 minutes from 8:34 a.m. next day.

Subtract 26 minutes from 8:34 a.m.:

- 8:34 a.m. – 26 minutes = 8:08 a.m.

✔ Answer: 8:08 a.m. (the next day)

*(Alternatively, you can add directly:*

*8:34 a.m. + 23 hours = 7:34 a.m. next day*

*7:34 a.m. + 34 minutes = 8:08 a.m. — same result!)*
