farmer has a 10-heactare maize farm. The maize is under “Fall Army Worm” attack. The farmer has to urgently control the attack using a chemical called AGENOX 221. Motorized sprayers with tank capacities of 15 litres each are to be used. The recommended concentration of the chemical is 2 ml/L and each full tank will cover ½ hectare. A 50-man team is engaged to control the attack. Using the above information and the assumptions given below: i. What volume of the chemical is required to cover the entire field to control the “Fall Army Worm” attack? ii. If each man covers an area of 25 m2 from one end of the field to the other, how many trips will each of them make to cover the entire field? Assume ach man moves in a straight line. Assumptions: 1. The 10 ha farm is considered to be a perfect square. 2. There is a 2.5 % loss of chemical due to the transfer to the sprayer tank.

3 A farmer has a 10-heactare maize farm. The maize is under “Fall Army Worm” attack. The farmer has to urgently control the attack using a chemical called AGENOX 221. Motorized sprayers with tank capacities of 15 litres each are to be used. The recommended concentration of the chemical is 2 ml/L and each full tank will cover ½ hectare. A 50-man team is engaged to control the attack. Using the above information and the assumptions given below:
i. What volume of the chemical is required to cover the entire field to control the “Fall Army Worm” attack?
ii. If each man covers an area of 25 m2 from one end of the field to the other, how many trips will each of them make to cover the entire field? Assume ach man moves in a straight line.
Assumptions:
1. The 10 ha farm is considered to be a perfect square.
2. There is a 2.5 % loss of chemical due to the transfer to the sprayer tank.
