## Answer :

Lets try this.

First calculate how many minutes are in the 5 hours.

60min*5=300min - in 5 hours

Now, knowing that quarter is 15min we can divide 300 by 15 to get the result, so

300:15=20 - its the result.

4/1 = x/5

cross multiply

1*x=4*5

x=20

there are 20 quarter hours in 5 hours.
