Question 863994: Nick, Kevin, and Joe can paint a room in 1 hour 20 minutes if the work together. Working alone, it takes Joe one hour more to complete the job than it takes Nick, and Nick works twice as fast as Kevin. How much time would it take each to complete the job working alone?
I convered to minutes and worked out that Nick works x minutes, Kevin 2x, and Joe x+1. Then , but when I solve, I don't get a real answer. I know that Nick works in 3 hours, but I don't know how to get that answer. Thanks for any help!
