Alexander and Judy are 32 miles apart on a calm lake paddling toward each other.
\n" ); document.write( " Alexander paddles at 4 miles per hour, while judy paddles at 7 miles per hour.
\n" ); document.write( " How long will it take them to meet?
\n" ); document.write( ":
\n" ); document.write( "Let t = their paddling time
\n" ); document.write( ":
\n" ); document.write( "When they meet, their travel distances will add up to 32: Dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "4t + 7t = 32
\n" ); document.write( ";
\n" ); document.write( "11t = 32
\n" ); document.write( "t = 32/11
\n" ); document.write( "t = 2.91 hrs or about 2 hrs 54.6 minutes
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check the solution by finding the distance of each:
\n" ); document.write( "2.91*4 = 11.64
\n" ); document.write( "2.91*7 = 20.37
\n" ); document.write( "-------------
\n" ); document.write( "total = 32.01 ~ 32 \n" ); document.write( "
\n" );
