The stopping distance d of a car after the brakes are applied varies directly as the square of the speed r. If a car traveling 60 mph can stop in 200 ft, how many feet will it take the same car to stop when it's traveling 70 mph?\r
\n" ); document.write( "\n" ); document.write( "---------------------
\n" ); document.write( "The distance is a function of the square of the speed.
\n" ); document.write( "The speed increases by a ratio of 7/6, so the distance increases by (7/6)^2
\n" ); document.write( "200*(7/6)^2 = 272.222... feet
