One day Eli set out for a trip across the lake on his motorboat at a rate
\n" ); document.write( " of 8 mph. Along the way the motor broke down. Eli rowed back at a rate of
\n" ); document.write( " 2 mph. He was gone for 5 hrs. How far did Eli row?
\n" ); document.write( ":
\n" ); document.write( "Let d = distance he rowed (and distance he went before he broke down)
\n" ); document.write( ":
\n" ); document.write( "Write a time equation: Time = \"dist%2Fspeed\"
\n" ); document.write( ":
\n" ); document.write( "Time motoring + time rowing = 5 hrs
\n" ); document.write( "\"d%2F8\" + \"d%2F2\" = 5
\n" ); document.write( "Multiply equation by 8:
\n" ); document.write( "d + 4d = 8(5)
\n" ); document.write( "5d = 40
\n" ); document.write( "d = \"40%2F5\"
\n" ); document.write( "d = 8 mi, he rowed his boat
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the times:
\n" ); document.write( "8/8 = 1hr
\n" ); document.write( "8/2 = 4hr
\n" ); document.write( "-----------
\n" ); document.write( "total 5 hr
