You can put this solution on YOUR website! Printer 1 prints a document in 10 minutes, printer prints a document in 22 minutes, if both machines worked together how long would it take to print a document?
.
Let x = time (minutes) it takes for both
then
x(1/10 + 1/22) = 1
multiplying bothsides by 220:
x(22 + 10) = 220
x(32) = 220
x = 220/32
x = 6.875 minutes
or
x = 6 minutes and 52.5 seconds
