Do the math

Alas, it's becoming more difficult for me to meet up with my regular running buddies. Besides C.B. getting ready to leave for the States for six months, M.B. has moved 10 miles out of town. It was so easy to schedule runs with M.B. when she lived a mile from my house right on my regular route! Last Saturday, I looked up directions to her new place and biked out there. I figured it would take me approximately three quarters of an hour, and in fact I got there in exactly 45 minutes. M.B. showed me around, then we looked at my map to find a suitable course. We saw that her village and the closest two others formed a neat triangle, so we decided to connect the dots. When I stopped my watch at the end of our run it read 45 minutes. After visiting some more and eating a delicious cookie, I cycled back to Lausanne. Another 45 minutes had gone by. I hadn't kept track of the time we spent touring the new house and chatting, but I got home precisely 3 hours after leaving that morning!

Gotta run...
