Question

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

Answer 1

Answer:

distance travelled by sound = speed × time => 340×4 = 1360m

Answer 2

Nita heard the sound after 4 sec

then,

t=4 sec

speed of sound=340m/s

d=?

As we know that,

d=s×t

then,

d=340×4

d=1360m

Hence,distance of lightning from Nita is 1360 m.

This is your required answer.

Hope it helps you
