Question

A person came to work at 8:30 AM, went out at 11:45 AM, had lunch, came in at 12:30 PM, and left work at 5:15 PM. The total number of hours worked by this person was a. 7 hours b. 7 hours, 15 min c. 8 hours d. 8 hours, 45 min

Answer 1

A person did his first shift from 8:30 AM to 11:45 AM.

The total hours in the morning were:

11 : 45

- 8 : 30

----------

3 : 15

3 hours and 15 minutes.

The second shift was from 12:30 PM to 5:15 PM.

To have the times easier subtracted, assume the final time was 5:30 PM (15 minutes in excess). The total time in the afternoon was:

5:30

- 0:30

----------

5:00

But we have to subtract 15 minutes, thus the total time in the afternoon was

4 hours and 45 minutes.

The total time was 3:15 + 4:45 = 8:00

Answer: 8 hours
