Question

A sound is heard 5 s later than lightning is seen on a rainy day find the the distance of the location of the lightning

Answer 1

Answer:

1.72 kilometres

Explanation:

Given :

• Time taken to hear the sound = 5 seconds

• Speed of the sound = 344 m/s

To find :

• Distance of the location of the lightning

Distance = speed × time

Distance = 344×5

Distance = 1720 metres

1000 metres = 1 kilometre

1720 metres = 1.72 kilometres

The distance of the location of the lightning is equal to 1.72 kilometres

Extra:

Time = distance / speed

Speed = distance / time

✒Given : -

• Speed of Sound = 344m/s
• Time Taken = 5 sec.

✒To Find : -

• Distance of Location of the lightning = ?

✒Formula Used : -

$\leadsto\sf{{ \large{ \bold{ \bold{ \bold{ \red{Distance=Speed\times{Time}}}}}}}}$

✒On Substituting Values : -

$\dashrightarrow\sf{D=344\times{5}}$

$\dashrightarrow\sf{D = 1720\:metres}$

✒In Kilometre : -

$\dashrightarrow\sf{1km=1000m}$

$\dashrightarrow\sf{So, 17200\:metres}$

$\leadsto\sf{{ \large{ \boxed{ \bold{ \bold{ \purple{1.72km}}}}}}}$
