Light travels extremely fast through the air, 300,000,000 m/s. Sound travels much slower, 343 m/s through air. Therefore we can see light in an instant, but it takes a while to hear thunder.

Explanation:

When you compare the numbers (speed of light vs speed of sound) you understand that light is 10^6 faster in speed that sound. When lightning occurs at a greater distance from the observer, this difference in speeds in more perceptible because the two different waves would have to travel greater distances to the observer and the relative differences in speed become increased.

Remember however, that sound travels in a medium while light waves do not require a medium because they are electromagnetic waves. In a vacuum, therefore, you would observe the lightning but never the sound.
