Waec Model Questions Vol2 2025 Mathematics Question 46
Practice objective / multiple choice question 46 from the 2025 Waec Model Questions Vol2 Mathematics examination.
The time \(T\) (in minutes) taken to fill a tank varies directly as the square of the flow rate \(f\) (in litres per minute) and inversely as the amount of water already in the tank \(w\) (in litres). When \(f = 4\) \(L/min\) and \(w = 200\) L, the tank is filled in \(5\) minutes. Find the flow rate required to fill the tank in \(3\) minutes if the amount of water initially present is \(150\) L.
