Practice objective / multiple choice question 4 from the 2020 Waec Model Questions Vol1 Geography examination.
Three cities - X, Y and Z - are to be linked to a new transport hub. The distances and terrain composition of the existing road segments are: - X-Y: 80 km (60 % flat, 40 % hilly) - Y-Z: 120 km (70 % flat, 30 % swamp) - X-Z: 150 km (50 % flat, 30 % hilly, 20 % swamp) Construction costs per kilometre are: flat = ₦5,000, hilly = ₦8,000, swamp = ₦12,000. If the hub is placed at city X, Y or Z, the hub must be connected by road to the other two cities using the existing segments.
