Neco Model Questions Vol1 2018 Mathematics Question 48
Practice objective / multiple choice question 48 from the 2018 Neco Model Questions Vol1 Mathematics examination.
The time \(T\) (in hours) required to finish a job varies directly as the square of the number of workers \(n\) and inversely as the number of machines \(m\), and also varies directly as the square root of the total weight \(W\) (in kilograms) of material processed. When \(n=4\) workers, \(m=3\) machines and \(W=200\) kg, the job takes \(6\) hours. How many hours will the same job take when \(n=6\) workers, \(m=5\) machines and \(W=450\) kg? Give your answer to two decimal places.
