Neco 2017 Geography Question 46
Practice objective / multiple choice question 46 from the 2017 Neco Geography examination.
A cargo ship must travel a round‑trip distance of 800 nautical miles at a constant speed \(v\) (in knots). Its fuel consumption per nautical mile is given by \(F = a + b v^{2}\) where \(a = 0.5\) litre/mi and \(b = 0.02\) litre/(mi·knots\(^{2}\)). The captain wants the total travel time not to exceed 48 h and the total fuel used not to exceed 2000 L.\n\n(a) Determine the range of speeds \(v\) that satisfy both the time and fuel constraints.\n\n(b) If the constraints cannot be met simultaneously, calculate the minimum fuel limit (in litres) that would make the trip feasible at the fastest allowable speed.
