Question 977201: Jacob 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 3420 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 60 miles more than twice the distance remaining until the finishing point. How far was Jacob from the finishing point of his journey when he made that calculation?
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! distance from starting point=x
2x-60+(x)=3420; distance remaining plus distance gone =total distance.
2x+x=3480
3x=3480
x=1160 miles.
He is 1160 miles from the start.
He has 2260 miles to go.
2260 is twice 1160, minus 60.
