How fast was the height of the water decreasing

Reference no: EM131015769

Water flows from a tank of constant cross-sectional area 60 ft² through an orifice of constant cross-sectional area 1/4 ft² located at the bottom of the tank. Initially, the height of the water in the tank was 20 ft, and t sec later it was given by the equation

2√h + (1/30)t - 2√20 = 0; 0 ≤ t ≤ 60√20.

How fast was the height of the water decreasing when its height was 9 ft?
