Neco Model Questions Vol1 2021 Biology Question 7

A car travels three road sections: Section A is \(12\) km at a speed limit of \(60\) km h\(^{-1}\); Section B is \(8\) km where the speed limit is reduced to \(40\) km h\(^{-1}\) because of construction; Section C is \(5\) km with a speed limit of \(80\) km h\(^{-1}\) but there is a traffic signal that forces a stop of \(2\) minutes. The car's fuel consumption is \(8\) L per 100 km at \(60\) km h\(^{-1}\). For each km h\(^{-1}\) above \(60\) km h\(^{-1}\) the consumption increases by \(0.05\) L per 100 km, and for each km h\(^{-1}\) below \(60\) km h\(^{-1}\) it decreases by \(0.04\) L per 100 km. What total amount of fuel, in litres, is consumed for the whole journey? Give your answer rounded to two decimal places.
