Paul and Peter can finish painting the fence in 2 hours. If Jane does the job alone she can finish it in 5 hours. If Paul does the job alone he can finish it in 6 hours. How long will it take for Peter to finish the job alone?
In two hour jane will finish 2/5 paul will finish 2/6 peter will finish = 1-(2/5+2/6) =1- (12/30+10/30) =1-(22/30) =8/30 =2/7.5 then he will finish it alone in 7.5 hours
