Rashid [163]

The expected time period between the observations of lightning and thunder would be 22.5 s.

How to calculate the time of sound waves?

The time taken by sound to reach a certain position can be calculated by the speed formula,

S = \dfrac dt

Where,

S - speed = 0.343 km/s

d - distance = 7.5 km

t - time = ?

Put the values in the formula,

0.343 = \dfrac {7.5} t\\\\t = \dfrac {0.343}{7.5}\\\\t = 22.5

Therefore, the expected time period between the observations of lightning and thunder would be 22.5 s.
