Your math teacher threw your cell phone off one of the overlooks on theBlue Ridge Parkway. The equation representing the path it took to the depths below is given by h(t) = -10t^2 + 10t + 60 where h(t) represents the height, in meters, of your phone and t represents the time it is in the air, in seconds. How long does it take your phone to smash to the ground?
