The number of miles required to reach the targeted average of 27.2 miles is 57.8 miles

  • Days per week = 7 days
  • Miles ridden = 17 miles
  • Targeted average = 27.2 miles

Targeted average = (miles ridden + 3m) / 7

27.2 = (17 + 3m) / 7

27.2 × 7 = 17 + 3.m

190.4 = 17 + 3m

3m = 190.40 - 17

3m = 173.4

m = 173.4 / 3

m = 57.8 miles

Therefore, the Number of miles per day is 57.8 miles
