The time T takes to buy a fuel at a petrol station varies directly as the number of vehicles V on a quare and inversely as the n
umber of pumps P available in the station. In a station with pumps, it took 10minutes to uel 20 vehicles. Find 1. The relationsip between T, P and V. 2. The time it will take to fuel 50 vehicles in the station with 2 pumps. 3. The number of pumps required to fuel 40 vehicles in 20 minutes.

A = w(2w + 3) 90 = 2w^2 + 3w 2w^2 +3w - 90 = 0 (w-6)(2w+15) = 0 (TRINOMIAL FACTORING) w = 6 inch ( it can't be -15/2 because lengths can't be negative) l = 2w + 3 = 15 inch
