Question

someone heard the sound of lighting after 4 seconds of seeing it. what was the distance of lighting from her?

Answer 1

They this question in incomplete.
But I will give u one example.
Velocity = 340m

Sol:-
velocity = distance / time
340. = distance / 4
Distance = 340/4
Distance = 80m/sec.
Hence, Distance of lighting from her is 80m/sec.

Plz give me brail list mark. I am requesting u plz.

Answer 2

Answer:

1360 m

Explanation:

Let someone is Nita

Suppose Nita is stood in open ground and she heard the lightning sound after 4 seconds of seeing it.

Given that,

Velocity of sound in air = 340 m/s

Time required = 4 seconds

To find: Distance between Nita and that Lightning

So,

Velocity = Distance / Time

340 m/s = Distance / 4 seconds

Distance = Velocity * Time

Distance = 340 * 4

Distance = 1360 meters

Therefore, the distance of Lightning from Nita is 1360 meters.
