Answer:
The correct answer is 52.5 miles per week.
Step-by-step explanation:
Miles rode by Matt Neibler in preparation for the "Hilly Hundred" bicycle ride = 787.5
Period of Matt preparation for the "Hilly Hundred" bicycle ride = 15 weeks
Average miles rode by Matt in the preparation cycle = Miles rode / period of preparation
Average miles a week rode by Matt in the preparation cycle = 787.5/15
Average miles a week rode by Matt in the preparation cycle = 52.5
