Question 1006140: Jack decided to ride his bicycle across the country during his 3-month summer vacation. The
route he took from Washington, DC to Portland, Oregon, covered a total of 3500 miles. To keep
his mind occupied during some of the long flat stretches of countryside, he often did algebra
problems in his head. One day, for example, he determined that his distance from his starting
point was exactly 80 miles more than twice the distance remaining until the finishing point.
How far was Jack from the finishing point of his journey when he made that calculation? Start
your work by defining the unknown quantities in terms of a variable.
