    well when you substitute the given information you get an equation \[h(t) = -16t^2 +110t + 150\] so how high is the object when it hits the ground...?

    great so let h(t) = 0 then \[-16t^2 + 110t + 150 = 0\] now solve for t only use the positive answer... you could use the general quadratic formula
