Answer: The runner’s average speed is 3 m/s.
Step-by-step explanation:
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).
So, mathematically speaking:
- 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
In conclusion, the runner’s average speed is 3 m/s.
