354688 A person places his ear at the end of a long steel pipe. He hears two distinct sounds at an interval of \(0.5\;s\) when another person hammers at the other end of the pipe. If the speed of the sound in metal and air are \(3630\;m{s^{ - 1}}\) and \(330\;m{s^{ - 1}}\) respectively, then the distance between the two persons is

1 \(90.75\;m\)
2 \(181.5\;m\)
3 \(363\;m\)
4 \(1650\;m\)
