Question

The track at the middle school is 200 meters. Rachel runs 1 ½ laps in 90 seconds. Find Rachel’s speed in meters/second

Answer 1

3.33 meters per second

Explanation:

1 1/2 laps = 200+100 = 300

use formula: distance = rate x time

t = time (in meter per second)

300 = 90t

t = 300/90 which reduces to 3.33/1
