A high school athlete runs 1.00 x 10 m in 12.20 s. What is the velocity in m/s and km/h?

Answer 1

0.8m/s and 2.91km/hr

Answer 2

`velocity = (distance)/(time) \\ velocity = (10)/(12.20) \\ velocity = (50)/(61) \\ multiply \: by \: 3.6u \: can \: convert \: to \: km \: per \: hour \\ velocity = (50)/(61) * 3.6 \\ v = (180)/(61) \\ v = 2.95 (km)/(h) \\ thank \: you`
