You can put this solution on YOUR website! Jenna is twice as far from the finish line as she is from the start of a 10 km race. how far has she ran?
--------------------
Let distance from start be "x" km.
Then distance from finish line is "2x":
----
Equation:
x + 2x = 10 km
3x = 10 km
x = 3 1/3 km (distance Jenna has run)
