Question

a boy fires a gun and another boy and distance here is a sound of fire 2.5 second after seeing the flash if speed of sound in air is 340 metre per second find the distance between the boys

Answer 1

Answer:

850 m

Explanation:

Here,

Speed of sound in air = 340 m/s

Time gap = 2.5 sec

Using speed = distance/time

Let the distance between them be d.

= > 340 = d/2.5

= > 340 * 2.5 = d

= > 850 m = d

Therefore the distance between the boys is 850 m
