A cyclist bikes x distance at 10 mph and returns over the same path at 8 mph. What is the cyclists average rate for the round trip in miles per hour.
\n" ); document.write( "------------------
\n" ); document.write( "x miles/10mph + x miles/8mph
\n" ); document.write( "=[8x+10x]/[80]
\n" ); document.write( "=18x/80
\n" ); document.write( "=(9/40)x hrs (This is total roundtrip time)
\n" ); document.write( "--------
\n" ); document.write( "Total distance is 2x miles
\n" ); document.write( "---------
\n" ); document.write( "Rate = distance/time = (2x)/[(9/40)x]= 80/9 mph
