Question 1171331: Bill Nye is launching a rocket for his next episode. The equation
h(t)=-16t^2+15t+600 gives the height of the rocket at any given time. How long will it take for the rocket to reach the ground? Round to the nearest hundredth.

To answer the question, you need to solve this quadratic equation


    -16t^2 + 15t + 600 = 0.


You will find two roots.


The greatest of the two roots will be your answer.

You are just instructed and directed. I encourage you to complete calculations on your own.
