Neco 2018 Mathematics Question 17
Practice objective / multiple choice question 17 from the 2018 Neco Mathematics examination.
The time \(T\) (in seconds) taken by a car to travel a distance \(d\) (in kilometres) varies directly with \(d\) and inversely with the square root of its engine power \(P\) (in kilowatts). When \(d=120\) km and \(P=90\) kW the car takes exactly 30 minutes. How many seconds will the car take to travel \(d=180\) km if its power is increased to \(P=160\) kW? Give your answer as an integer number of seconds.
