Jill is 13.5 kilometers away from Joe.
\n" ); document.write( "Both begin to walk toward each other at the same time.
\n" ); document.write( " Jill walks at 3 kilometers per hour. They meet in 3 hours.
\n" ); document.write( " How fast is Joe walking?
\n" ); document.write( ":
\n" ); document.write( "Let s = Joe's walking speed
\n" ); document.write( ":
\n" ); document.write( "write a distance equation: dist = time * speed,
\n" ); document.write( "the distances each person walks adds up to 13.5 km
\n" ); document.write( ":
\n" ); document.write( "Jill's dist + Joe's dist = 13.5 km
\n" ); document.write( "3(3) + 3s = 13.5
\n" ); document.write( "3s = 13.5 - 9
\n" ); document.write( "3s = 4.5
\n" ); document.write( "s = \"4.5%2F3\"
\n" ); document.write( "s = 1.5 km/hr is Joe's crawling speed
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check; find the dist of each:
\n" ); document.write( "3(3) = 9 km
\n" ); document.write( "3(1.5)= 4.5 km
\n" ); document.write( "--------------
\n" ); document.write( "total 13.5 km \n" ); document.write( "
\n" );
