Neco Model Questions Vol1 2021 Agricultural Science Question 1
Practice objective / multiple choice question 1 from the 2021 Neco Model Questions Vol1 Agricultural Science examination.
A farmer uses a disc plough that is 0.75 m wide. To ensure complete tillage each pass must overlap the previous one by 10 % of the plough width. The field to be tilled is a rectangle 120 m long and 45 m wide. The farmer can operate the plough at a constant speed of 5 km h\(^{-1}\).\n\n(a) How many hours (to two decimal places) will be required to till the whole field with this disc plough?\n\n(b) If the farmer replaces the disc plough with a mouldboard plough that is 0.50 m wide, can increase his speed by 20 % but must still maintain the same 10 % overlap, how many hours (to two decimal places) will be required with the mouldboard plough?
