4. A water trough is 8 m long, and a cross section has the shape of an isosceles triangle that is 100 cm wide at the top with a height of 60 cm. The trough is full of water but the valve on the bottom is open and water is pouring out at a rate of 3mmin How fast is the water level dropping when the water in the tank is only 20 cm deep?
