Two boats left an island at the same time to return to their home port.
\n" ); document.write( "Their average speeds differ by 4MPH. The faster boat reaches the port after 3 hours. The slower boat took thirty minutes longer. Find the speed of each boat?
\n" ); document.write( "--------------
\n" ); document.write( "Faster boat DATA:
\n" ); document.write( "time = 3 hrs ; rate = x mph ; distance = rt = 3x miles
\n" ); document.write( "--------------------------
\n" ); document.write( "Slower boat DATA:
\n" ); document.write( "time = 3.5 hrs ; rate = (x-4)mph ; distance = rt = 3.5(x-4) miles
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "3x = 3.5x-14
\n" ); document.write( "-0.5x = -14
\n" ); document.write( "x = 28 mph (speed of the faster boat)
\n" ); document.write( "x-4 = 24 mph (speed of the slower boat)
\n" ); document.write( "==========================================
