Homework Statement
If 15 workers can pave 18 driveways in 24 days, how many days would it take 40 workers to pave 22 driveways
Homework Equations
Actually i don't know which equation should be used for 3 quantities. I know the eq for two quantities.
Because we increasing labours so we would require less days
Workers * days/ increased workers (i.e constant product eq)
The Attempt at a Solution
I can find days using above eq:[/B]
15 * 24/40 = 9 days
For 18 drive ways we need 9 days
For 1 drive way , we would need 18/9 = 2 days
For 22 driveways, we would need 11 days.
Is there a simple method for solving the above problem.
