A bicyclist rode into the country for 5 h. In returning, her speed was 5 mi/h
\n" ); document.write( " faster and the trip took 4 h. What was her speed each way?
\n" ); document.write( ":
\n" ); document.write( "Let s = her speed into the country (To commune with nature, no doubt)
\n" ); document.write( "Then (s+5) = her speed returning from the country (Chased by a bear possibly!)
\n" ); document.write( ":
\n" ); document.write( "Distance = time * speed
\n" ); document.write( ":
\n" ); document.write( "Dist out = Dist back
\n" ); document.write( "5s = 4(s+5)
\n" ); document.write( "5s = 4s + 20
\n" ); document.write( "5s - 4s = 20
\n" ); document.write( "s = 20 mph out, 25 mph back
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check using distance:
\n" ); document.write( "out: 5(20) = 100 mi
\n" ); document.write( "back 4(25) = 100 mi \n" ); document.write( "

\n" );
