A bullet is fired horizontally at a target, and the sound of its impact is
\n" ); document.write( " heard 1.5 seconds later.\r
\n" ); document.write( "\n" ); document.write( "If the speed of the bullet is 3300ft/sec and the speed of sound is
\n" ); document.write( " 1100ft/sec , how far away is the target?
\n" ); document.write( ":
\n" ); document.write( "Let d = distance to the target
\n" ); document.write( "Write a time equation: time = dist/speed
\n" ); document.write( ":
\n" ); document.write( "Bullet transit time + sound return time = 1.5 sec
\n" ); document.write( " $\"d%2F3300\"$ + $\"d%2F1100\"$ = 1.5
\n" ); document.write( "multiply eq by 3300, results
\n" ); document.write( "d + 3d = 3300(1.5)
\n" ); document.write( "4d = 4950
\n" ); document.write( "d = 4950/4
\n" ); document.write( "d = 1237.5 ft \n" ); document.write( "

\n" );
