Question

sound produced by thunderstorm is heard 10 second after the lighting is seen calculate the approximate distance of the thunder cloud given speed of sound in air= 340 M per second

Answer 1

Speed of sound in air=344m/s
Time=10sec
Velocity=2d/t
344=2d/10
3440=2d
1720=d
The cloud is at a distance of 1720m.

Answer 2

To calculate the distance from the velocity of any object,we generally use v=2d/t formula.

And, according to the given circumstances in the question, the distance of the thunder cloud is;

v=2d/t

340=2d/10

2d=3400

d=1700

The distance of that thundercloud is approximately 1700 m or 1.7 km (answer.)
