Question

Nicole's aerobics class exercises to fast paced music. If the rate of the music is 120 beats per minute, how many beats would be there in a class that is 0.75 hours long?

a) 90
b) 160
c) 5400
d) 7200

Answer 1

(.75)(60) = 45 minutes -- .75 of an hour is 45 minutes
120 (45) = 5400

I think I did this correctly, but you might want to get a second opinion :)
