A meeting started at 10:35 a.m. and ended at 3:15 p.m. of the same day. how long was the meeting?

To find the duration of the meeting, we need to calculate the time elapsed between 10:35 a.m. and 3:15 p.m.

First, let's convert the time to a 24-hour format for easier calculation.

10:35 a.m. = 10:35
3:15 p.m. = 15:15

Next, we subtract the start time from the end time:

15:15 - 10:35 = 4 hours and 40 minutes

Therefore, the meeting lasted for 4 hours and 40 minutes.

To calculate the duration of the meeting, you need to subtract the start time from the end time.

Step 1: Convert the start and end times to minutes.

- Start time: 10:35 a.m. can be converted to 10 * 60 + 35 = 635 minutes.
- End time: 3:15 p.m. can be converted to 15 * 60 + 15 = 915 minutes.

Step 2: Subtract the start time from the end time.

915 minutes - 635 minutes = 280 minutes.

Therefore, the duration of the meeting is 280 minutes.
