30 machines = 60 days
The number of machines is inversely proportion to the number of days:
⇒ more days, less machine
⇒ more machines, less days
Find the number of machines needed if the job has to be completed in 1 day:
60 days = 30 machines
1 day = 60 x 30 = 1800 machines
Find the number of machines needed if the job has to be completed in 40 days:
1 day = 1800 machines
40 days = 1800 ÷ 40 = 45 machines
Answer: 45 machines are needed to complete the job in 40 days.
