## College Physics (4th Edition)

We can find the time required to complete the run at an average rate of 4.0 m/s: $v_{av} = \frac{distance}{time}$ $time = \frac{distance}{v_{av}}$ $time = \frac{1000~m}{4.0~m/s}$ $time = 250~s$ Since Massimo has already used 250 seconds to complete 900 meters, it is impossible for Massimo to complete the run in 250 seconds. Massimo can not pass the test.
