Worked Solution
The concert ended at 4:45 p.m. and lasted 2 hours 35 minutes.
To find the start time, subtract the duration from the end time.
Step 1: Subtract the 2 hours.
4:45 p.m. − 2 h = 2:45 p.m.
Step 2: Subtract the 35 minutes.
2:45 p.m. − 35 min = 2:10 p.m.
The concert started at 2:10 p.m.
Check: 2:10 p.m. + 2 h 35 min = 4:45 p.m. ✓
Correct answer: 2:10 p.m.
