Neco 2023 Agricultural Science Question 47
Practice objective / multiple choice question 47 from the 2023 Neco Agricultural Science examination.
A farmer can either use a tractor‑drawn disc plough or a hand hoe to prepare a \(10\) ha field for planting. The disc plough is \(2.5\) m wide, the tractor can travel at \(5\) km h\(^{-1}\) in the field and the field efficiency for mechanised work is \(75\%\). The hand hoe has an effective width of \(0.5\) m, the farmer can work at \(2\) km h\(^{-1}\) and the field efficiency for manual work is \(60\%\).\n\nCalculate the time (in hours, rounded to the nearest whole hour) saved by using the tractor‑drawn plough instead of the hand hoe to prepare the whole field.
