You can put this solution on YOUR website!
60t - 5t^2 = 27
arrange as a quadratic equation
-5t^2 + 60t - 27 = 0
looks like this, green line is 27 meters
+graph%28+300%2C+200%2C+-6%2C+15%2C+-20%2C+180%2C+-5x%5E2%2B60x-27%2C+27%29+
use the quadratic formula, a=-5, b=60, c=-27
:
Two solutions, nearest hundredth
t = .47 seconds on the way up
t = 11.53 seconds on the way down
