A Water Trough Is 20 M Long and a Cross-Section $0.7 \mathrm{~m}^{3} / \min$

question 8

Short Answer

A water trough is 20 m long and a cross-section has the shape of an isosceles trapezoid that is 20 cm wide at the bottom, 60 cm wide at the top, and has height 50 cm. If the trough is being filled with water at the rate of $0.7 \mathrm{~m}^{3} / \min$ , how fast is the water level rising when the water is 25 cm deep? Round the result to the nearest hundredth.
