Since B is in between both points, then:

This gives


Divide by 3

Step-by-step explanation:
-2x=30-120
-2x = -90
=x = -90/-2
=x = +45
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
