Answer:
I believe the answer would be 2,400 minutes over four weeks of practice.
Step-by-step explanation:
2.5x4=10
that is 10 minutes a week. you need to find four weeks so you would multiply more.
10x4=40
there is 60 minutes in an hour so you need to multiply more.
40x60=2,400
so that is your answer, 2,400 minutes.
