Neco 2023 Mathematics Question 23
Practice objective / multiple choice question 23 from the 2023 Neco Mathematics examination.
The time \(t\) (in hours) required to finish a job varies directly as the square of the number of workers \(w\) and inversely as the square of an efficiency factor \(e\). If 6 workers with efficiency \(e = 0.8\) complete the job in 5 hours, how many workers are needed to complete the same job in 4 hours if the efficiency is reduced to \(e = 0.5\)? Express your answer in simplest radical form.
