In Physics
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.

The speed of lightning is somewhere between that of light and sound which is why most scientists would agree that the speed of light and the speed of sound make a good comparison to that of lightning and electricity.

# Is it really true that the lightning strikes first before the thunder or the lightning and thunder strikes together but only the lightning seems to be first because of it's speed of light?

Lightning does indeed strike first, as thunder is the sound created by lightning. According to Wikipedia, lightning heats the air surrounding it by large quantities, which in turn causes the air to expand and create a "Sonic wave" which is similar to a sonic boom.

# What is the speed of sound and lightning?

sound travels through our atmosphere at approximately 330 m/s. lightning is just a huge flash of electricity from the cloud to the earth and back. the light we see given off from the strike travels at about 2.99x10^8 m/s.
