Practice objective / multiple choice question 6 from the 2023 Neco Agricultural Science examination.
A farmer has a rectangular field of \(15{,}000\ \text{m}^2\) (1.5 ha). A plough can be set to a working width of \(0.5\ \text{m}\) at a forward speed of \(5\ \text{km/h}\). If the width is increased to \(0.75\ \text{m}\) the speed drops by 20\% (i.e., to \(4\ \text{km/h}\)). The farmer wishes to finish ploughing the whole field in no more than \(6\) hours.
