if 5 secs. elapse between a lightning flash and the clap of thunder ,how far away is the strom ?speed of sound =332 m/s

Open in App

Solution

Let x be the distance travelled by the lightning and thunder.
Then the time taken by light to travel is $\frac{x}{3 \times 10^{8}}$
Time taken by the sound to travel is $\frac{x}{332}$
Hence
$5 = \frac{x}{332} - \frac{x}{300000000} x = \frac{5 \times 332 \times 300000000}{(300000000 - 332)} x = 1660 m approximately$

Let x be the distance travelled by the lightning and thunder. Then the time taken by light to travel is x3×108 Time taken by the sound to travel is x332 Hence 5=x332-x300000000x=5×332×300000000300000000-332x=1660m approximately
