 Question 122701: Mark can overhaul an engine in 20 hours and Phil can do the same job by himself in 30 hours. If they both work together for a time and then Mark finishes the job by himself in 5 hours, how long did they work together? Here is the work I've tried on this problem, for some reason I can't figure out the last part, the 5 hours part. Here's what I've got so far: T(1/30 + 1/20) = 1 T(2 + 3) = 60 5T = 60 T = 12 So when they work together, it would take them 12 hours total, right? Then I need the last part: Would it be 12 hours minus the rate of Mark's last 5 hours? 12 - 5(1/20)= T ? T = 11.75? They worked together for 11 hours and 45 minutes? Please let me know if I'm on the right track or if I'm way off. I hope I haven't confused you as much as I've confused myself! Thanks! Click here to see answer by ankor@dixie-net.com(15622)
