Question 244123
Scott and Dan are traveling together. First Scott drives one fifth of the way. Then Dan drives one third of the remaining distance. Next Scott drives one half of the remaining distance, and finally Dan drives the last 80 miles. What is the total distance traveled? How far does each person drive. 
--------------------
After Scott drives 1/5, 4/5 is left.
After Dan drive 1/3, 2/3 of 4/5 is left = 8/15 left.
Scott then drives half of that, so 4/15 is left, and is 80 miles.
Total = 80/(4/15) = 300 miles.
---------
Knowing the total, you can find the distances.
