Practice objective / multiple choice question 27 from the 2019 Neco Model Questions Vol1 Mathematics examination.
The speed \(s\) (km/h) of a car varies directly as the engine power \(P\) (kW) and inversely as the square of the total mass \(M\) (tonnes). When \(P=80\) kW and \(M=1.6\) t, the car travels at \(100\) km/h. If the engine power is increased by \(25\%\) and the mass is increased by \(20\%\), what is the new speed (to the nearest kilometre per hour)?
