How far, will it travel in 2 hours 12 minutes, if it continues at the same constant speed? \n" ); document.write( "----- \n" ); document.write( "distance = rate*time \n" ); document.write( "Notice that rate and time are indirectly related (as one increases the other decreases. \n" ); document.write( "------------------- \n" ); document.write( "Your Problem:: \n" ); document.write( "30km in 15 min implies 4*30 km in 4*15 min or 120 km/hr \n" ); document.write( "-------------------------------- \n" ); document.write( "Ans: dist = rate*time \n" ); document.write( "dist = 120 km/hr * 2hr 12 min = 120(2 1/5) = 120(11/5) = 24*11 = 264 km \n" ); document.write( "============ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "---------- \n" ); document.write( " |
