WAEC Mathematics 2024 Theory — Question 1

1. The time (t) taken to buy fuel at a filling station varies directly as the number of vehicles (V) in a queue and varies inversely as the number of pumps (P) available at the station. In a station with 5 pumps, it took 10 minutes to fuel 20 vehicles. Find the: (a) relationship between t, P and V; (b) time it takes to fuel 50 vehicles at a station with 2 pumps; (c) number of pumps required to fuel 40 vehicles in 20 minutes.
