Answer:
19 calls
Step-by-step 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:
19 calls
Step-by-step explanation:
4 hours + 45 minutes
= 4 * 60 minutes + 45 minutes
= 240 + 45
=285 minutes
[tex]no \: of \: phone \: calls \\ = \frac{285}{15} \\ = 19 \\ [/tex]
Hence, 19 calls could be made.
