A farmer intends to plough a rectangular field measuring 180 m by 120 m using a tractor‑drawn plough that turns a strip 1.2 m wide per pass. The tractor can travel at \(4\ \text{km h}^{-1}\) while ploughing, but each time it reaches the end of a pass it must turn, which adds 2 minutes to the operation. The farmer wishes to complete the ploughing in 6 hours. (a) Determine whether the field can be ploughed within the allotted time. (b) If it cannot, calculate the minimum plough width (in metres, to two decimal places) required to finish the work in 6 hours, assuming the travelling speed remains unchanged.

Answer Options

A. No, the farmer cannot finish within 6 hours. Minimum plough width ≈ 1.20 m
B. Yes, the farmer can finish within 6 hours. Minimum plough width ≈ 1.56 m
C. No, the farmer cannot finish within 6 hours. Minimum plough width ≈ 2.00 m
Correct Answer D. No, the farmer cannot finish within 6 hours. Minimum plough width ≈ 1.56 m
Correct Answer
D
Correct Option:
No, the farmer cannot finish within 6 hours. Minimum plough width ≈ 1.56 m
