Question 105765
 since we know that she traveled on the same path, the distance going to the mountain and the distance going home should be equal. Thus, the final equation shoul be: 30x = 20(5-x) >>> 30x = 100 - 20x >>> 50x = 100 >>> x = 2

* take note that x in this equation is the time it took her to go to the mountain and distance equals (speed)(time). Thus the answer is equal to 60m
