Question

Wild Animal Park tours start at 9:30 a.m. on Saturdays and leave every 15 minutes until 12:45 p.m. How many tours are there during that time? Explain your work.

Answer 1

Simple.

You take 9:30, and you increase the time by 15 minutes until you reach 12:45 P.M. You know that there are 60 minutes in an hour. (Technically there are 59). So, let's begin.
9:30 <- The start time
9:45
10:00
10:15
10:30
10:45
12:00
12:15
12:30
12:45 <- End time

Now just count the time changes from 9:30 to 12:45.
Answer = 8.
So there are 8 tours taken until 12:45 PM

This one was really simple. The trick is to know how to record and read time.
