# Find the distance between the fort and the man :

A gun is fired from a fort. A man hears the sound 10 second later. If the sound travels at the rate of 330 m/sec, find the distance between the fort and the man.

- 3.3 km
- 0.33 km
- 33 km
- 330 km

**Answer: (1) 3.3 km **

**Explanation:-**

The speed of the sound = 330 m/sec

A man hears the sound 10 second later.

Then, the distance between the fort and the man = 330 x 10

= 3300 m

As we know that 1000 m = 1 km

Therefore, 3300 m = 3300/1000

= 3.3 km

Hence, the correct answer is option (1) 3.3 km.
