Use unit multipliers to convert 400 yards per second to miles per hour. \n" ); document.write( "---------------- \n" ); document.write( "Change to yards/hour \n" ); document.write( "--- \n" ); document.write( "Include the units in the calculations. \n" ); document.write( "400 yd/sec * 3600 sec/hr = 1440000 yd/hr - notice the seconds cancel. \n" ); document.write( "----- \n" ); document.write( "1440000 yd/hr * 1 mile/1760 yd = 1440000/1760 yd*mile/hr*yd \n" ); document.write( "The yards cancel \n" ); document.write( "=~ 818.2 mi/hr \n" ); document.write( "===================== \n" ); document.write( "Including units makes it obvious and avoids multiplying when you should divide and v.v. \n" ); document.write( " \n" ); document.write( " |
