Question

A sprinter ran a 100 meter dash in 12.5 seconds. What was his speed?'

Answer 1

Speed is (pretty much) the same thing as velocity.

Velocity can be calculated by dividing the distance traveled over the time it took to travel said distance.

V=d/t

V=100 meters/12.5 seconds=8 meters per second

Velocity=8 m/s

Answer 2

Answer:

Velocity 8 m/s

I really hope this helps ;D
