Algebra.Com's Answer #412700 by vleith(2983)![]() ![]() ![]() You can put this solution on YOUR website! Let the time required for the faster firework to reach the correct height be t. \n" ); document.write( "Then the time for the slower firework is \n" ); document.write( "You know that the height for both is the same. You also know that the distance to that distance is given by \n" ); document.write( "\n" ); document.write( "You are told the speed for both fireworks. \n" ); document.write( "So \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So 5 seconds after the faster one gets fired, they will both explode at a height of 1100 feet.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
