Solve Word Problems Using Quadratic Equations

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height “y” in feet of the water “t” seconds after its release is modeled by:

The horizontal distance “x” in feet between the water and its point of release is modeled by:

x = 91t

At what horizontal distance should the pilot release the water in order to hit the target?

goal: find “x”
