who can answer this question i can mark at brainlist

Answer 1

Answer:

Given:

Velocity of sound in air (v) = 346 m/s

Time required (t) = 2 seconds

To Find:

Distance between person hearing and that Lightning

Solution:

We Know That,

General Formula,

$\blue{\boxed{\boxed{\sf velocity = \dfrac{distance}{time} }}}$

$\red{\implies \sf 346 \;m/s= \dfrac{distance}{2\;s}}$

$\purple{\implies \sf distance = (346 \times 2)\;m}$

$\orange{\implies \sf distance = 692 \;m}$

Therefore,

The Distance between person hearing and that Lightning is 692 m
