Suppose that the amount of time it takes to build a highway varies directly with the length of the highway and inversely with the number of workers. suppose also that it takes 200 workers 3 weeks to build 2 miles of highway. how many miles of highway could 250 workers build in 6 weeks?

W = 5 miles

Explanation:

Work done by 200 worker in 3 week is equivalent to build 2 miles highway

So we will have

work done by each worker in 3 week is equivalent to

now work done in each week is given as

now we have to find the work done by 250 workers in 6 weeks

so we will have
