From a common starting position, willy and jessica ride their bikes in opposite directions. Willy rides 2 km faster than jessica. in 3 hours, the two are 60 km apart. find the average speed of each one.
\n" ); document.write( "Let jessica's rate be x km/h
\n" ); document.write( "Then willy's rate is x+2 km/h
\n" ); document.write( "------
\n" ); document.write( "They are separating at a combined rate of 2x+2 km/h
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "time*rate = distance
\n" ); document.write( "3*(2x+2) = 60
\n" ); document.write( "2x+2 = 20
\n" ); document.write( "2x = 18
\n" ); document.write( "x = 9 km/h (Jessica's rate)
\n" ); document.write( "x+2 = 11 km/h (Willy's rate)
