Waec Model Questions Vol1 2023 Mathematics Question 6
Practice objective / multiple choice question 6 from the 2023 Waec Model Questions Vol1 Mathematics examination.
The time T (in minutes) taken to fill a tank varies directly as the square of the radius r (in cm) of the inlet pipe and inversely as the speed v (in cm min⁻¹) of water flow. When \(r = 4\) cm and \(v = 6\) cm min⁻¹, the tank is filled in 5 minutes. If the radius is increased to 5 cm and the required filling time is 3 minutes, what speed of water flow (in cm min⁻¹) is needed?
