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

i think this could be a possible answer (1 / 84) -1
