Question

Nita heard the sound of lightning after 4 seconds of seeing it. What was the distance of the lightning from her. (The velocity of in air is 340m\s?)

Answer 1

speed=d*t
340=d*4
340*4=d
1360m=d

Answer 2

Answer:

1360 m

Explanation:

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 = 340 * 4

Distance = 1360 meters

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