1. Time Problem: When did Roman’s soccer practice start?

> Given:
> - Roman ended his soccer practice at 4:45 P.M.
> - He was there for 1 hour and 30 minutes.

We need to find the start time.

- Subtract 1 hour:
4:45 P.M. – 1 hour = 3:45 P.M.
- Subtract 30 minutes:
3:45 P.M. – 30 minutes = 3:15 P.M.

✔ Answer: Start Time = 3:15 P.M.
