At the second meeting, together they went a distance of 3 bridge lengths.

They continue to the opposite ends, for a total of two bridge lengths. Finally they turn around and meet again for a total of 3 bridge lengths. On the first leg, the slower cyclist has gone 2,000 feet. So at the end he will have cycled three times this distance or 6,000 feet. Subtracting the 720 feet he has cycled on the return trip leaves a bridge length of 5,280 feet (or exactly 1 mile).<BR/><BR/><B>Answer:</B><BR/>The bridge is exactly 1 mile long.Blainehttps://www.blogger.com/profile/06379274325110866036noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-5504821675967020672008-08-07T10:46:00.000-07:002008-08-07T10:46:00.000-07:00might take me all summermight take me all summerRalph Loizzohttps://www.blogger.com/profile/16194974915716525500noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-90356020256657905542008-08-06T14:16:00.000-07:002008-08-06T14:16:00.000-07:00Good luck folding that map back up! :-)Good luck folding that map back up! :-)Blainehttps://www.blogger.com/profile/06379274325110866036noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-26952072495123562692008-08-06T13:58:00.000-07:002008-08-06T13:58:00.000-07:00It is!

Even the hard way was pretty mild though; just had to deal with 3 variables and a generous number of equations with which solve those 3 variables.Kevinhttps://www.blogger.com/profile/16166996163671225643noreply@blogger.com
