Question 383526
John can finish his homework in 10 minutes.
 A fellow student would finish it up at a different rate.
 Both students working together can do the homework in 8 minutes.
 How long does it take the second student to complete the homework if working alone?

Let x = time required by fellow student alone
Let the completed homework = 1
:
A typical shared work equation
{{{8/10}}} + {{{8/x}}} = 1
solve for x
