Z=8
Sebastian ran 1.44 miles in the last 24 minutes. First, divide 8.64 by 2.4 to get 3.6 miles per hour. Since the question is asking for the last 24 minutes, divide 3.6 by 60 which gives you 0.06. Then, just multiply the rate per minute by 24 which gives you how many miles he ran in the last 24 minutes of his run.
