A bicyclist rode into the country for 5 hours. In returning, her speed was 5 mile per hour faster and the trip took 4 hours. What was her speed each way?
\n" ); document.write( ":
\n" ); document.write( "Let s = speed into the country
\n" ); document.write( "It says return speed was 5 mph faster, therefore:
\n" ); document.write( "(s+5) = return speed
\n" ); document.write( ":
\n" ); document.write( "We know the distance there and back are the same so write a distance equation:
\n" ); document.write( "Remember Dist = time * speed
\n" ); document.write( ":
\n" ); document.write( "5s = 4(s+5)
\n" ); document.write( ":
\n" ); document.write( "An easy equation \n" ); document.write( "
