Tom bikes 15 km/hr faster than Bill.
\n" ); document.write( "In the time it takes Tom to bike 80 km, Bill has ridden 50 km.
\n" ); document.write( "So, Tom is 30 km ahead of Bill.
\n" ); document.write( "That means he has been riding 30 km/15 km/hr = 2 hr to get that far ahead.
\n" ); document.write( "Tom's rate is 80 km/ 2 hr = 40 km/hr
\n" ); document.write( "Bill's rate is 50 km / 2 hr = 25 km/hr
\n" ); document.write( "
\n" );
