A computer printer can print a 660-word document in 35 seconds. At this rate, how many seconds are required to print a document that contains 840 words?
660/35 = 840/x
Cross multiply and solve for x.
To find out how many seconds are required to print a document containing 840 words, we can use a proportion.
First, we need to set up the proportion using the given information:
660 words = 35 seconds
840 words = x seconds
Now we can cross-multiply and solve for x:
660x = 840 * 35
To find x, divide both sides of the equation by 660:
x = (840 * 35) / 660
Simplifying this expression gives us:
x = 44.54545454545455
Therefore, it would take approximately 44.55 seconds to print a document with 840 words at the same rate as the given printer.
