It takes Bobby 60 minutes longer to wax the car than it does his brother Kevin. Together it takes them 50 minutes to wax the car. How long does it take each working separately?

**Steve**, Thursday, January 31, 2013 at 10:28amIf Kevin takes x minutes,

1/50 = 1/(x+60) + 1/x

x = 10(2+√34) =~ 78.3

So

Kevin takes 78.3 minutes,

Bobby takes 138.3 minutes.
