A soldier fired two bullets at an interval of 335 seconds moving at a uniform speed V₁. A terrorist who was running ahead of the soldier in same direction, hears the two shots at an interval of 330 seconds. If the speed of sound is 1188 km/h, then who is the faster and how much?

Explanation:-

Speed of sound / relative speed of soldier and terrorist = Time taken / Difference in time
¹¹⁸⁸/_S = ³³⁰/₅
S = 18 km/h.
