Solution

Two shots were fired at an interval of 6 minutes, but the man heard both shots at an interval of 5 minutes 52 seconds which means that between the hearing of the first shot and the second shot, he covered a distance equal to 330*8 m.

Time taken by man to cover the distance = 352 seconds

Speed of man = (330*8)/352 = 7.5 m/s

Speed in Km/hr = 7.5 * (18/5) = 27 Km/hr
