Question 140
A gun is fired from a fort. A man hears the sound 10 seconds later. If the sound travels at the rate of 330 m/sec, find the distance between the fort and the man.
Solution
Speed = 330 m/sec and time = 10 seconds
Using, distance = speed $$\times$$ time
=> Distance between the fort and the man = $$330\times10=3300$$ m
= $$\frac{3300}{1000}=3.3$$ km
=> Ans - (A)
