One hour is 60 minutes. A quarter of an hour is 60 minutes/4 = 60/4 minutes = 15 minutes. Three quarters of an hour = 3*a quarter of an hour = 3*15 minutes = 45 minutes.
There are 2 quarters hours in half an hour and a quarter of an hour is 15 minutes while half an hour is 30 minutes
There are 45 minutes between 3:00 and a quarter to four.
195 minutes.
