The printer's rate of work is R = 12 pages/minute, and the total amount of work is W = 30 pages. Using the work equation R x T = W, you can solve for the time: \(T = \frac{W}{R}=\frac{30}{12}=2 \frac{1}{2}\) minutes. However, the question asks for the answer in seconds. Because there are 60 seconds in each minute, you must multiply 2.5 x 60 to arrive at the correct answer of 150 seconds.
