Algebra.Com's Answer #248091 by haileytucki(390)![]() ![]() You can put this solution on YOUR website! A bullet is fired horizontally at a target, and the sound of its impact is heard 1.5 seconds later. If the speed of the bullet is 3300ft/sec and the speed of sound is 1100 ft/sec how far away is the target? \n" ); document.write( "Let the target be at a distance of x feet . \n" ); document.write( "Time taken by bullet to reach the target = x/3300 seconds \n" ); document.write( "Time taken by sound to reach the ear is = x/1100 seconds \n" ); document.write( "The total time taken is 1.5 seconds \n" ); document.write( "x/3300 + x/1100 = 1.5 \n" ); document.write( "x+3x / 3300 = 1.5 \n" ); document.write( "4x= 3300 * 1.5 \n" ); document.write( "4x= 4950 \n" ); document.write( "x= 4950 /4 \n" ); document.write( "1237.50 \n" ); document.write( "The distance of the target is 1237.50 feet. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
