ross pay) plus income tax (on the gross pay before the social security deduction). There is a progressive tax system for calculating income tax, where the first $10,000 is tax free, and anything above $10,000 is taxed at 25%.

We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.
