If the 1st machine runs 2 hours and the 2nd machine runs 3 hours and 560 washers are produced, how many does each one produce in one hour?Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website!``` Hi, Let x represent the number Of washers the second machine can produce in one hour Then 2x is the number Of washers the first machine can produce in one hour Write as we Read 2hr *2x/hr + 3hr*x/hr = 560 washers solve for x 4x + 3x = 560 7x = 560 x = 80, number Of washers the second machine can produce in one hour (2*80) Or 160 is number Of washers the first machine can produce in one hour checking our answer 2*160 + 3*80 = 560 ```
