An Olympic runner completes the 200-meter sprint in 23 seconds. What is the runner’s average speed? (Round your answer to the nearest tenth of a meter per second.) 0.9 m/s

Respuesta :

Since speed=distance/time, you would divide the distance (200 meters) by 23 seconds. Your answer rounded up to the nearest tenth is 8.7 seconds

divide the distance by the time, since you want the answer in meters per second there are no other conversions required.

200/23 = 8.6956 meters per second

 round to nearest tenth would be 8.7
