Question

In 4 hours and 45 minutes, what is the greatest number of phone calls that could be made if each call lasts 15 minutes? Show each of the steps for solving the problem.​

Answer 1

19 calls

Explanation:

Let’s see if each call lasts 15 minutes just divide 45 by 15 and you get 3.

Then for the 4 hours how many 15 minutes are in a hour, 4!

So if there are 4 hours and there are 4 calls each hour then in total there is 16 calls.

Then you add up the 3 calls and 16 calls and you get 19 calls!

Answer 2

19 calls

Explanation:

4 hours + 45 minutes

= 4 * 60 minutes + 45 minutes

= 240 + 45

=285 minutes

`no \: of \: phone \: calls \\ = (285)/(15) \\ = 19 \\`

Hence, 19 calls could be made.
