A cyclists completes a journey of 1500m in 66sec, part of the way at 10m/s and the remainder at 50m/s.
\n" ); document.write( " How far does he travel at each speed?
\n" ); document.write( ":
\n" ); document.write( "Let t = time at 50 m/s
\n" ); document.write( "then
\n" ); document.write( "(66-t) = time at 10 m/s
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( "50t + 10(66-t) = 1500
\n" ); document.write( "50t + 660 - 10t = 1500
\n" ); document.write( "50t - 10t = 1500 - 660
\n" ); document.write( "40t = 840
\n" ); document.write( "t = 840/40
\n" ); document.write( "t = 21 sec at 50 m/s
\n" ); document.write( "then
\n" ); document.write( "21*50 = 1050 meters at 50 m/s
\n" ); document.write( "and
\n" ); document.write( "66-21 = 45 sec at 10 m/s
\n" ); document.write( "then
\n" ); document.write( "45 * 10 = 450 meters at 10 m/s \n" ); document.write( "
\n" );
