A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = -16t^2 + 22t + 3, where t is the time in seconds. In addition, the function d(t) = 85t models the horizontal distance d traveled by the ball. If no one catches the ball, how long will it stay in the air?

you'll want to find the roots of the function h(t), otherwise said, the t values for which h(t) = 0.  The biggest (latest) t value is the answer you're looking for.

d(t) is not needed for answering this question since horizontal travel is independent of vertical travel
