Lightning is the exchange of energy and plasma. According to scientist Bruce Steo, lightning moves at variable speeds. Lightning is in fact not light. But as the electronic plasma moves through charged air, it releases light waves. Depending on air conditions, the typical lightning bolt moves at 224,000 mph -- or about 3,700 miles per second.
However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.
Lightening travels at 300,000 km per second which is the same speed as light.

Light travels at 186,000 miles per second in a vacuum. So the light from a flash of lightning travels at the speed of light in air, which is slightly less than the speed of light in a vacuum (e.g. space)
But lightning itself travels nowhere near as fast as the speed of light. Lightning is an electrical discharge and is bound by the laws of physics. Its speed depends on many factors, including the conductivity of the medium it is travelling through. Careful scientific measurements of many lightning flashes have revealed that the electricity moves at different speeds at different stages of its journey in the lightning flash. Also, its returning upstroke is much faster than its downstroke.
Speed of Propagation
The Guinness Book of Answers indicates maximum speeds around 87,000 miles per second. Also, the US Department of Energy gives the speed of lightning as 93,000 miles per second, which may be based on the 'half the speed of light' principle. Neither is considered accurate for atmospheric discharges.
Observed Velocity
Propagation of high-altitude lightning observed from space was measured at a speed of 50 kilometers per second (112,000 mph). This is considerably slower than the 670 kilometers per second (1,500,000 mph) maximum return stroke velocity reported in an IEEE report in 2006. In a paper published in 2007, wide variations in stroke speeds were reported, up to 4000 kilometers per second (9,000,000 mph). While incredibly fast, these show that the average lightning speed is considerably slower than the speed of light.

lightning is able to strike 100 times per second.
As fast as a bolt of lightning.
Lightning can be used as a noun (bolt of lightning) or an adjective (lightning fast). It is not a verb, so it does not have a past tense form.
"Lightning" is a noun. Sometimes people try to use it as an adjective to mean "fast" (ex, "with lightning speed") but it really should be used as "like lighting" or "lightning-fast" or so on.
The idiom "quick as greased lightning" means extremely fast or rapid, like lightning that is slick and fast due to being lubricated with grease. It is used to describe someone or something that moves or acts very quickly.
Some examples of fast things include cheetahs running, lightning striking, and Formula 1 cars racing.
fast
I believe you mean "why does it matter how fast sound can travel?" There are many reasons for why it matters to know how fast sound travels. it can help with determining the distance of a lightning storm, tuning instruments, and is helpful with ballistics. -Tychusfindlay919
Approx. 270,000 mph or about 75 miles per second. Lightning creates light but is an exchange of energy and is, therefore subject to friction so it does not travel the speed of light.
A high-speed jet is nowhere near as fast as a lightning bolt.
The guy who is fast as lightning is usually referred to as "The Flash".

So fast. kachow!
