Hi,

 A man can weed his yard in 3 hours. His son can do the same job in 2 hours.

 how long highlight_green%28x%29 would it take them if they worked together?

 +1%2F3+%2B+1%2F2+=+1%2Fx   ||Multiplying thru by 6x so as all denominators = 1

      2x + 3x = 6

       5x = 6

        x = 6/5 hr  0r  1 1⁄5 hr 0r 1hr and 12min
