we are asked to find how many quarter hours are there in 5 hours
quarter as a fraction is 1/4
so quarter hour is 1/4th fraction of an hour
1 hour = 60 minutes
1 hour is made of 4 quarter hours
therefore 5 hours have - 4 quarter hours/ hour x 5 hours = 20 quarter hours
there are 20 quarter hours in 5 hours
