The average rate of change of the runner is 0.667 mph
Rate of change = change in distance / change in time
Time:
Initial time, t1 = 0.5
Final time, t2 = 2
Distance :
Initial distance, d1 = 1.5
Final distance, d2 = 2.5
Rate of change = (d2 - d1) / (t2 - t1)
Rate of change = (2.5 - 1.5) / (2 - 0.5)
Rate of change = 1.0 / 1.5
Rate of change = 0.667 mph
