George and William both ran a one mile race. William won the race with a time of 4 minutes and 30 seconds. If George was 480 feet behind William when the race finished, how long did it take George to run the entire mile? (George continued to run at the same pace.)

When the race was done, George completed:
5280 feet in a mile - 480 feet = 4800 feet

set up a proportion of distance traveled to time where n is the time needed to run the mile
4800/4.5 = 5280/n

Using our proportion calculator, we get:
n = 4.95

5280/4800 = 1.1

Setup another proportion with the 1.1 factor of distance to time:
4800 * 1.1/4.5 * 1.1 = 5280/4.95


4.95 = 4 minutes and .95*60 seconds
4.95 = 4 minutes and 57 seconds
