Question Statement:

Answer Key:

200

Step-by-Step Solution & Explanation

Width $W = 12 \times 0.5 = 6.0\text{ m}$. Speed $S = 5.4\text{ km/h}$. Total $Q = 12 \times 0.9 = 10.8\text{ L/min} = 648\text{ L/h}$. Coverage $= (6 \times 5.4)/10 = 3.24\text{ ha/h}$. Rate $= 648 / 3.24 = 200.0\text{ L/ha}$.
