Answer:

  28 miles

Step-by-step explanation:

Let w stand for the number of miles Derrick runs each week. Then after 4 weeks of training, he wants the total mileage to be 100 miles.

  16 + 3w = 100

  3w = 84 . . . . . . . subtract 16

  w = 28 . . . . . . . . divide by 3

Derrick will run 28 miles each week to achieve his training goal.
