Question

During a thunderstorm, the thunder is heard 2.5 s after the flash of lightning is seen. If the speed of sound is 330m/s . Find the distance at which lightning took place.​

Answer 1

Given:

Time after which the thunder was heard = 2.5 sec

Speed of sound = 330 m/s

To find:

Distance at which lightning took place.

Solution:

As we know that speed = distance travelled / time

Therefore distance travelled = speed * time

Putting the values of speed and time we get:

Distance = 330 * 2.5

Distance = 825 m

Therefore the time at which lightning took place = 825 m.

Answer 2

Answer:

825

Explanation:

Given:

Time after which the thunder was heard = 2.5 sec

Speed of sound = 330 m/s

To find:

Distance at which lightning took place.

Solution:

As we know that speed = distance travelled / time

Therefore distance travelled = speed * time

Putting the values of speed and time we get:

Distance = 330 * 2.5

Distance = 825 m

Therefore the time at which lightning took place = 825 m.
