Running for his life, Riley travels 100 m in 9.83 s. What was his average velocity in m/s and km/h?

Asked by Anne16

Answer (2)

100m / 9.83 sec = 10.17 m/s (rounded)
There are 3,600 seconds in an hour.
(100 m / 9.83 sec) x ( 3600 sec/hr) = 36,622.6 m/hr = 36.62 km/hr
That's about 22.8 miles per hour.

Riley's average velocity is approximately 10.17 m/s. When converted to kilometers per hour, his average velocity is about 36.67 km/h. These calculations use the formulas for average velocity and conversion from meters per second to kilometers per hour.
