evin Briley began a 114 mile bicycle trip to build up stamina for a triathlete competition.
\n" ); document.write( " Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 6 hours. If Kevin walks at a rate of 4 miles per hour and rides at 24 miles per hour, find the amount of time he spent on the bicycle.
\n" ); document.write( ":
\n" ); document.write( "let t = time spent on the bike
\n" ); document.write( "The whole trip took 6 hr, therefore
\n" ); document.write( "(6-t) = his time walking
\n" ); document.write( ":
\n" ); document.write( "write a distance equation; dist = speed * time
\n" ); document.write( "24t + 4(6-t) = 114
\n" ); document.write( "24t + 24 - 4t = 114
\n" ); document.write( "24t - 4t = 114 - 24
\n" ); document.write( "20t = 90
\n" ); document.write( "t = 90/20
\n" ); document.write( "t = 4.5 hrs on the bike
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, he must have spent 1.5 hrs walking
\n" ); document.write( "24 * 4.5 = 108 mi
\n" ); document.write( "4 * 1.5 = 6 mi
\n" ); document.write( "----------------
