A runner is participating in a 10.7mile race. If the runner stopped at a water station that is twice as far from the starting line as from the finish line, how far is the runner from the finish line?


Expert Answer

Step 1

The total distance of the race is 10.7 miles.


It is given that, the runner stopped twice as far from the starting line as from the finish line.

Step 2

That is, two times from the starting point and one time from ending point.


In algebraic expression the total distance of the race is 2x + x.

Step 3

Equate the expression 2x + x into the total distance to find the travelled distance of the runner from the starting point.


2x + x = 10.7

      3x = 10.7
