Answer:

22.5 s is the correct answer to the given question .

Explanation:

Given that

d=7.5km=7.5\times 10^3 m

For light:

We know that speed of light c

c=3\times 10^8 m/s

We know that

Distance = Speed \times timed=C\time tt=\dfrac{D}{t}t=\dfrac{7.5\times 10^3}{3\times 10^8}\ st=2.5\times 10^{-5}st=0.025 ms

For thunder :

Speed of sound ,v=332 m/s

Time\  taken\  by\  sound \\t\’=\dfrac{7500}{332}=22.59 s

Therefore the difference between time is given as follows

\Delta t= t' - \ t=22.59-2.5\times 10^{-5}=22.59 s

22.5 is the answer
