A practical test is arranged to compare the efficiency of a hand hoe and a small motorised plough in turning over the topsoil of a field. The test plot is a rectangular area of 2 m × 1 m, divided into two equal sections of 1 m × 1 m. Each section is prepared to a uniform depth of 0.15 m. A stopwatch is used to record the time taken to turn over the soil in each section, and a ruler is used to verify the depth. The recorded times are: hand hoe – 12 minutes; motorised plough – 3 minutes. The farmer intends to cultivate a total area of 0.5 ha (5 000 m²) using either tool.

Question Parts

( a )
Calculate the average rate of soil turnover (in cubic metres per minute) for each tool.
( b )
State the ratio of the productivity of the motorised plough to the hand hoe and comment on what this implies for a small‑holder farmer.
( c )
Estimate the total time required to prepare the entire 0.5 ha using each tool. Based on these estimates, advise which tool is more appropriate for a small‑holder farmer who has limited financial resources but wishes to finish the work within a fortnight (14 days).
