tortoise goes 15 cm/sec; rabbit goes at 240 cm/sec or 2.4 m/sec.
\n" ); document.write( "so tortoise wins by 15/20 or 0.75 sec\r
\n" ); document.write( "\n" ); document.write( "the race takes s sec
\n" ); document.write( "tortoise went 15s cm
\n" ); document.write( "rabbit went 15s-20 cm
\n" ); document.write( "the rabbit's time running was 240 cm/sec and ran for (s-174) seconds, since 2.9 min is 174 sec
\n" ); document.write( "Then, 240 cm/sec *(s-174) sec=15s-20 cm \r
\n" ); document.write( "\n" ); document.write( "240s-41760=15s-20
\n" ); document.write( "225s=41740
\n" ); document.write( "s=185.51 seconds, or 3m5.51s\r
\n" ); document.write( "\n" ); document.write( "The tortoise went, in that time, 27.83 m or 2783 cm
\n" ); document.write( "The rabbit spent all but 11.51 sec resting, so the distance in 11.51 sec was 27.624 m, 0.2 m or 20 cm fewer.
\n" ); document.write( " \n" ); document.write( "
