Russ and Janet are running in the Apple Hill Fun Run. Russ runs at 7 mph, Janet at 5 mph. If they start at the same time, how long will it be before they are 1/2 miles apart?
\n" ); document.write( ":
\n" ); document.write( "Let t = required time for them to be 1/2 mile apart
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation: dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "Rus's dist - Jan's dist = 1/2 mile
\n" ); document.write( "7t - 5t = 1/2
\n" ); document.write( ":
\n" ); document.write( "2t = 1/2
\n" ); document.write( ":
\n" ); document.write( "4t = 1; multiplied by 2, gets rid of the denominator
\n" ); document.write( ":
\n" ); document.write( "t = 1/4 of an hr: In 15 min they will be 1/2 mile apart
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( "7(1/4) - 5(1/4) =
\n" ); document.write( "7/4 - 5/4 = 2/4 = 1/2 mile \n" ); document.write( "
\n" );
