Neco 2017 Mathematics Question 50
Practice objective / multiple choice question 50 from the 2017 Neco Mathematics examination.
The time \( t \) (in minutes) taken to fill a tank varies directly as the volume \( V \) (in litres) and inversely as the square root of the pump's power \( P \) (in kilowatts). If a 200‑litre tank is filled in 12 minutes by a 4‑kW pump, how long will it take to fill a 450‑litre tank using a 9‑kW pump?
