[CV085] Weekend Getaway

Distances both to and from your destination were exactly the same. On the way there, you drove 180 miles, and on the way home, you drove one way minus 150 miles.

Think about the distance your girlfriend drove. On the way there, she drove one way minus 180 miles. On the way home, she drove 150 miles.

The total distance each person drove must include the trip out and the trip back. If you combine the earlier information about each leg of the trip, you'll see that your girlfriend drove a total of "one way minus 30 miles."

Using the principle in Hint Two and the information from Hint One, you can express the distance you drove as "one way plus 30 miles."

With that said, the difference between the distance you drove and the distance your girlfriend drove should be clear as day.
