A farmer has a plough whose working width can be set to either \(0.5\) m or \(1.2\) m. The field size is \(5\) ha. For a \(1\) m wide plough the normal working rate is \(0.8\) ha per hour. The wider plough reduces the effective rate by \(20\%\) because of the heavier draft. Which plough width will finish the field sooner and by how many hours does it save work?

Answer Options

A. Use the \\ (1.2) m plough; it saves roughly \\ (4) hours compared with the \\ (0.5) m plough.
Correct Answer B. Use the \(1.2\) m plough; it saves roughly \(6\) hours compared with the \(0.5\) m plough.
C. Use the \\ (0.5) m plough; it saves roughly \\ (4) hours compared with the \\ (1.2) m plough.
D. Use the \\ (0.5) m plough; it saves roughly \\ (6) hours compared with the \\ (1.2) m plough.
Correct Answer
B
Correct Option:
Use the \(1.2\) m plough; it saves roughly \(6\) hours compared with the \(0.5\) m plough.
