1. Problem Description

Ruby starts reading her book at 7:50 PM. She reads for 1 hour and 5 minutes. We need to find what time she finishes reading.

2. Solution Steps

We are given that Ruby starts reading at 7:50 PM and reads for 1 hour and 5 minutes. We need to add 1 hour and 5 minutes to 7:50 PM.
First, add 1 hour to 7:50 PM.
7:50 PM +1 hour =8:50 PM 7:50 \text{ PM } + 1 \text{ hour } = 8:50 \text{ PM }
Next, add 5 minutes to 8:50 PM.
8:50 PM +5 minutes =8:55 PM 8:50 \text{ PM } + 5 \text{ minutes } = 8:55 \text{ PM }
Therefore, Ruby finishes reading at 8:55 PM.

3. Final Answer

8:55 PM
