45 minutes.

Explanation:

1 hour is 60 minutes, and there are four 15 minute intervals. So, if there are four intervals of 15 minutes that add up to 60, just take three of them and put them over four:

#(15*15*15)/(15*15*15*15) = 45/60#

Or we could multiply one hour, or 60 minutes, by #3/4#.

#60 * 3/4 = 60/1 * 3/4 = (60*3)/(4*1) = 180/4 = 45#

Three fourths of an hour is 45 minutes.
