Neco Model Questions Vol1 2018 Geography Question 21

A cargo of goods must be transported 240 km from point A to point B. Two possible routes are available:\n\nRoute 1: Fully paved road. Average speed = \(60\) km/h. Toll = \(\text{₦}1,500\) per 100 km. Fuel consumption = \(8\) L per 100 km.\n\nRoute 2: Mixed road - 150 km paved and 90 km unpaved. On paved sections speed = \(55\) km/h and fuel consumption = \(7\) L per 100 km; on unpaved sections speed = \(35\) km/h and fuel consumption = \(9\) L per 100 km. No tolls. Fuel price = \(\text{₦}165\) per litre.\n\nThe cargo must be delivered within \(5\) hours and the company wants the minimum total cost (toll + fuel). Which route should be chosen and what is the total cost (in naira) of the chosen route? State the answer as "Route X, total cost = \(\text{₦}Y\)".
