Hi, Previously Posted

If Mary can paint one room in 100 minutes, and Jake can paint one room in 150 minutes, 

how longhighlight%28x%29  will it take if they work together?

Question states*** PER min Key

 1%2F100+%2B+1%2F150+=+1%2Fx   |Multiplying thru by 300x so as all denominators = 1

 3x + 2x = 300

    5x = 300

     x = 60min or 1 hr together
