A hawk flying at 20 m/s at an altitude of 187m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation y=187-x^(2)/60 until it hits the ground, where is its height above the ground and is the horizontal distance traveled in meters. Calculate the distance traveled by the prey from the time it is dropped until the time it hits the ground.
