Derrick is training for a race he wants to run a total of 100 miles over 4 weeks he only runs 16 miles in the first week if he runs the same number of miles in each of the last three weeks how far will he run each week

  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.
