Owen harvested 2400 hectares of canola in 12 days using 4 machines. How long would it take to harvest 3600 hectares if he used 6 machines?

1 answer

2400 hectares of canola in 12 days using 4 machines

600 hectares of canola in 12 days using 1 machine

3600 hectares of canola in 12 days using 6 machines

or

time is directly proportional with the acreage and inversely with the number of machines

T = k (A/M)
given:
12 = k(2400/4)
12 = 600k
k = 12/600 = 1/50

T = A/(50M)
so when A = 3600, and M = 6
T = 3600(50(6)) = 12
