Answer:
This is because speed of sound in air is less than speed of light.
Explanation:
Here we know that speed of sound in air is around 330m/s and light is 3×10^8m/s.So the light of the thunder comes first not the sound.

The speed of light is 3,00,000 KMPS
The speed of sound is about 300 MPS

speed of sound × Time
300×5
=1500M
