1 second

Step-by-step explanation:

Using -b/2a I can get the maximum height of the ball. Assuming that there is no outside forces, there should be an equal time of going up and coming down, so if max height is at 1/2 seconds, then it should take 1 full second for the ball to hit the ground.

x/3-10=8

x/3=18

x=48

0.5?
