A bicycle rider travels 18 miles in the same amount of time that it takes a jogger to travel 10 miles. If the bicyclist goes 9.6 miles per hour faster than the jogger, how fast does each person travel?
\n" ); document.write( ":
\n" ); document.write( "distance = rate * time
\n" ); document.write( ":
\n" ); document.write( "let r be the rate of the jogger...therefore rate of the bike rider is r+9.6
\n" ); document.write( "times are equal
\n" ); document.write( ":
\n" ); document.write( "bike:18=(r+9.6)t...eq 1
\n" ); document.write( "jogger:10=rt.......eq 2
\n" ); document.write( ":
\n" ); document.write( "rewrite eq 2 to t=10/r and plug that into eq 1
\n" ); document.write( ":
\n" ); document.write( "18=(r+9.6)(10/r)
\n" ); document.write( ":
\n" ); document.write( "18r=10(r+9.6)......multiplied both sides by r
\n" ); document.write( ":
\n" ); document.write( "18r=10r+96
\n" ); document.write( ":
\n" ); document.write( "8r=96
\n" ); document.write( ":
