Step 1 :Let's denote the rate of the slower computer as S, the rate of the faster computer as F, and the rate of both computers together as T.
Step 2 :We know that S = \(\frac{1}{45}\) jobs per minute and T = \(\frac{1}{15}\) jobs per minute.
Step 3 :We can set up the equation T = S + F and solve for F.
Step 4 :Substituting the values of S and T into the equation, we get \(\frac{1}{15} = \frac{1}{45} + F\).
Step 5 :Solving for F, we get F = \(\frac{1}{15} - \frac{1}{45} = 0.04444444444444444\) jobs per minute.
Step 6 :The time it takes for the faster computer to do the job on its own is the reciprocal of its rate, so time_for_faster_computer = \(\frac{1}{F} = 22.500000000000004\) minutes.
Step 7 :Final Answer: The faster computer will take approximately \(\boxed{22.5}\) minutes to do the job on its own.
