Answer 1

Answer:

5832 metres is the required answer.

Explanation:

According to the Question

It is given that ,

• Time taken to heard the thunderstorms ,t = 18s
• Speed of Sound in air ,S = 324m/s

we need to calculate the how far from him/her the lighting reach the ground . Obviously we have to calculate the distance covered by sounds in the given condition.

Let the distance covered by the sound is d m .

We know that

• Distance covered = speed of light × time

Substitute the value we get

➺ d = 324×18

➺ d = 5832 m

➺ d = 5832 metres

• Hence, the lighting was about 5832 metres far from you.

Answer 2

Given :-

Speed of sound = 324 m/s

Time = 18 s

To Find :-

Distance

Solution :-

We know that

Distance = Time × Speed

Distance = 18 × 324

Distance = 5832 m
