Question 35287: Jim and Bob are painters. Jim can paint a wall in 6 hours and Bob can do the same size wall in 4 hours. How long will it take to paint the wall if Jim and Bob work together? Your answer is supposed to have the form h hour and m minutes, where h and m are positive integers. Put h in the 1st box with the unit hr, and put m in the 2nd box with the unit min.

You can put this solution on YOUR website! Set-up the problem as follows:
x/6 + x/4 = 1 (one entire job)
Simplify and solve for "x"
(6x + 4x)/24 = 1
10x/24 = 1
x = 24/10
x = 2.40 hours
Convert .40 hours to minutes by using the conversion factor of 60 minutes/1hour:
.40hours x (60min)/(1hr)= 24 minutes
So both men would complete the job in 2 hours and 24 minutes.
