Question

A Girl stand at a distance of 240 away from a world shoot a rifle and hear a Eco after 1.2 seconds calculate the velocity of sound.​

Answer 1

Answer:

In this question we will use formula t=2d/v

12/10= 480/v

Cross multiple 12v= 4800

V= 4800/12

Then v =400

Answer 2

Answer:

we know that speed = Distance

time

then, it is given that

Distance= 240

time =1.2

Now ,

velocity =?

according to the formula mentioned above velocity means speed

so, velocity= 240

1.2

= 2400

12

=200
