If Becky worked from 9:15 am to 1:30 pm, how many hours did she work?

To determine how many hours Becky worked from 9:15 am to 1:30 pm, we can break down the calculation of the time interval step by step.

First, calculate the total number of hours and minutes she worked:

1. From 9:15 am to 10:15 am is 1 hour.

2. From 10:15 am to 1:15 pm is an additional 3 hours.

3. Finally, from 1:15 pm to 1:30 pm is an additional 15 minutes.

Now, adding this up:

• 1 hour + 3 hours = 4 hours

• Adding the 15 minutes gives a total of 4 hours and 15 minutes.

Thus, the total time Becky worked is indeed 4 hours and 15 minutes, making this the correct answer. This calculation methodically breaks down the time interval into manageable segments to arrive at the precise amount of time worked.
