Neco 2019 Mathematics Question 21
Practice objective / multiple choice question 21 from the 2019 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 pressure \(P\) (in kPa). If it takes 12 minutes to fill a 300‑litre tank when the pressure is 9 kPa, how long will it take to fill a 450‑litre tank when the pressure is increased to 16 kPa?
