You can put this solution on YOUR website! Ok...we use s = d/t.
You are given the speed to be 10 meters per second.
I need to know the distance d to solve for t (in hours).
Understand?
The question is asking you to find the value of t but this cannot be done without knowing the height, which is called distance in this question.
So far we have this: 10 = d/t.
