New Hampshire has over 50 covered bridges. The three longest are the PittsburgClarksville Bridge which is ninetyone feet long, the Happy Corner Bridge which is eightysix feet long, and the River Road Bridge which is fiftyseven feet long. If you laid these bridges end to end, how long would the new bridge be?

The wind blew my hat away. I ran and ran after it. At last I caught it. Then I had to walk home. I walked three blocks to Main Street, then I walked six blocks to Elm Street, and then I walked four blocks to my house. How many blocks did I walk to get home?
