Answer:
15 minutes
Step-by-step explanation:
One hour contains 60 minutes. Take 60 and divide it by the total number of parts ( four, you get 15 minutes per fourth of an hour. )
Then find how many parts you want (one) 1 part is equal to 15 minutes in this problem.
1/4 of an hour is 15 minutes. 1/2 an hour is 30 minutes so half of that is 15 minutes
