Physics

A student throws a ball vertically upward such that it travels 9.0 m to its maximum height. If the ball is caught at the initial height 2.4s after being thrown, what is the ball's average speed?

I know average speed is change in distance over change in time, but I don't know how to get those numbers.

Thank you.

  1. average speed= distance/time= 18m/time
