Ed and Alice walked to the dock at 5 miles per hour, jumped into the boat and motored to Destin at 15 miles per hour. If the total distance was 20 miles and the trip took 2 hours in all, how far did they go by boat?
\n" ); document.write( "---------------------
\n" ); document.write( "Walk DATA:
\n" ); document.write( "rate = 5 mph ; time = x hrs ; distance = 5x miles
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Boat DATA:
\n" ); document.write( "rate = 15 mph ; time = 2-x hrs ; distance = 15(2-x) miles
\n" ); document.write( "------------
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 20 miles
\n" ); document.write( "5x + 30-15x = 20
\n" ); document.write( "-10x = -10
\n" ); document.write( "x = 1 hr (walking time)
\n" ); document.write( "2-x = 1 hr (boat time)
\n" ); document.write( "Boat distance = 15x = 15 miles
