each other at an interval of 1 2 seconds regularly the echo of the
first clap coincides with the fifth clap if the speed of sound in

Pratyay Ghosh · Accepted Answer

The fifth clap happens 1 2×4=4 8 sec after the
first clap In this time interval the sound travels 340×4
8=1632 m,
So the wall is 16322=816 m away from the man
