Jackie is standing on a bridge looking at the river below. She throws a rock over the bridge with an initial velocity of 60 feet per second. If the height, h, of the rock at time t seconds after it was thrown can be modeled by the equation h = -16t^2 + 60t + 72, to the nearest tenth of a second, how long will it take the rock to reach the surface of the water?
