Waec Model Questions Vol1 2024 Agricultural Science Question 1
Practice objective / multiple choice question 1 from the 2024 Waec Model Questions Vol1 Agricultural Science examination.
A farmer uses a hand hoe that tills 1.2 m² per minute. The hoe becomes dull after each hour of continuous work, reducing its efficiency by 20 % for the next hour unless it is sharpened. Sharpening restores the original efficiency and takes 10 minutes. The farmer must till a field of 0.18 hectare (1 ha = 10 000 m²). Assuming the farmer sharpens the hoe only when necessary and works in whole‑hour blocks, what is the minimum total time (in hours) required to till the whole field, including sharpening time?
