'Find the number of hour s from 11:30am to 3:30pm

To find the number of hours between 11:30am and 3:30pm, you can subtract the starting time from the ending time.

First, let's start by converting both times to a 24-hour format for easier calculation.

11:30am is equivalent to 11:30 in the 24-hour format.
3:30pm is equivalent to 15:30 in the 24-hour format.

Now, to calculate the difference, subtract the starting time from the ending time:

15:30 - 11:30 = 4:00

Therefore, there are 4 hours between 11:30am and 3:30pm.
