Weekend Getaway is the 85th puzzle from The Curious Village.
You and your girlfriend went on a road trip over the weekend. On the way to your destination, you drove 180 miles, and your girlfriend drove the rest of the way. Coming home on the exact same roads, your girlfriend drove the first 150 miles and then you got behind the wheel for the last leg of the journey. So what is the difference in miles between the distance you drove and the distance your girlfriend drove?
