d=15*t
\n" ); document.write( "d=25*(t-2.5)\r
\n" ); document.write( "\n" ); document.write( "15t=25(t=2.5)
\n" ); document.write( "15t=25t-62.5
\n" ); document.write( "-10t=-62.5
\n" ); document.write( "t=6.25 hours\r
\n" ); document.write( "\n" ); document.write( "So it took Colleen 3 hours 45 mins (from the time Colleen started) to catch Kacie.
