Kacie started on her bike at 15 miles per hour. Colleen left 2 and 1/2 hours later traveling at a rate of 25 miles per hour. How long did it take her to catch Kacie?
\n" ); document.write( "-----------------------
\n" ); document.write( "Kacie DATA:
\n" ); document.write( "rate = 15 mph ; time = x hrs ; distance = rt = 15x miles
\n" ); document.write( "--------------------------
\n" ); document.write( "Colleen DATA:
\n" ); document.write( "rate = 25 mph ; time = x-(5/2) hrs ; distance = rt = 25x-62.5 miles
\n" ); document.write( "----------------------------
\n" ); document.write( "If one catches the other their distances are equal:
\n" ); document.write( "Equation:
\n" ); document.write( "15x = 25x - 62.5
\n" ); document.write( "10x = 62.5
\n" ); document.write( "x = 6.25 hrs (Kacie's time)
\n" ); document.write( "---
\n" ); document.write( "x-(5/2) = 3.75 hrs (Colleen's time to catch Kacie
\n" ); document.write( "==============================
