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?

B. Terrorist, 25 km/h

C. Soldier, 18 km/h

D. Terrorist, 20 km/h

E. None of these

Answer: Option C

Solution(By Examveda Team)

$$\frac{{{\text{Speed }}\,{\text{of }}\,{\text{sound}}}}{{{\text{Relative speed of soldier and terrorist}}}} = $$         $$\frac{{{\text{Time }}\,{\text{taken}}}}{{{\text{Difference }}\,{\text{in }}\,{\text{time}}}}$$
$$\frac{{1188}}{{\text{S}}} = \frac{{330}}{5}$$
Soldier = 18 km/h
