\n" ); document.write( " When he reaches his dock, he finds that he has been gone for 5 hours.
\n" ); document.write( " How far has he rowed?
\n" ); document.write( ":
\n" ); document.write( "Let d = distance rowed (same as by motor)
\n" ); document.write( ";
\n" ); document.write( "Write a time equation. Time = \"distance%2Fspeed\"
\n" ); document.write( ":
\n" ); document.write( "Motor time + rowing time = 5 hrs
\n" ); document.write( "\"d%2F8\" + \"d%2F2\" = 5
\n" ); document.write( ":
\n" ); document.write( "Multiply equation by 8 to get rid of the denominators, results:
\n" ); document.write( "d + 4d = 8(5)
\n" ); document.write( ":
\n" ); document.write( "5d = 40
\n" ); document.write( "d = \"40%2F5\"
\n" ); document.write( "d = 8 miles rowed
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in our equation
\n" ); document.write( "\"8%2F8\" + \"8%2F2\" = 5
