document.write( "A cockroach can run at about 2mph. The average body length of a cockroach is about 1 inch. The average body length of a horse is 8 feet. If we asume that a horse's speed-to-length ratio is the same as that of a cockroach, how fast can a horse run? \n" );

Algebra.Com's Answer #19655 by sarah_adam(201)![]() ![]() ![]() You can put this solution on YOUR website! cockroach = speed : length = 2:1 ( 1 in ) \n" ); document.write( "horse = speed : length = s:8 (8ft ) \n" ); document.write( "so lets convert ft to in \n" ); document.write( "1ft = 12 in \n" ); document.write( "8ft = 8 *12 = 96in\r \n" ); document.write( "\n" ); document.write( "now according to the assumption \n" ); document.write( "2:1 = s:96 \n" ); document.write( "2/1 = s/96 \n" ); document.write( "s = 2*96= 192 mph \n" ); document.write( "speed of horse = 192 mph \n" ); document.write( " |
