What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Hi, to solve this problem we have to multiply the length of the track (402.2 meters) by the times that joe ran around it (8.25 times).

Mathematical expression is:

402.3m x 8.25 = 3,318.975 meters

Now that we have this result, we have to divide it by the time ( 1,119.803 sec), to obtain the speed rate.

3,318.975 m/ 1,119.803 sec = 2.97m/sec= 3 m/s

Therefore the runner’s average speed is 3 m/s the correct option is C.
