Neco 2019 Geography Question 46
Practice objective / multiple choice question 46 from the 2019 Neco Geography examination.
A bus travels from town A to B covering \(120\) km and then from B to C covering \(80\) km. On the first segment the driver may choose any constant average speed \(v\) (km/h) between 40 and 80. Fuel consumption on this segment is given by \(f(v)=0.05v+2\) litres per 100 km. On the second segment the speed is fixed at \(60\) km/h and fuel consumption is \(8\) litres per 100 km. Fuel costs \(\text{₦}150\) per litre and the driver is paid \(\text{₦}500\) per hour of operation (including wage and other costs). Determine the speed \(v\) that minimises the total operating cost (fuel plus driver wage) and state the minimum cost (to the nearest naira).
