Question 440285: The number of cars varies jointly as the number of workers and the hours they work. If 200 workers can produce 60 cars in 2 hours, find the constant of variation and the joint variation equation
(Use the following variables: Cars (c) Workers (w) hours (h)
Use this equation to determine how many cars 240 workers should be able to produce in 3 hours.

If 200 workers can produce 60 cars in two hours, then one worker can make 30/200 car per hour, or 3/20th of a car, per person, per hour.
--------------------
240x3x3/20=12x9=108 cars..
