Light travels at about 670 million miles per hour.
It would take approximately 40,238 years to travel 20 light years at 36,000 mph. This calculation takes into account the limitations of current space travel technology and the vast distances involved in interstellar travel.
It is 670,616,629 mph.
A car traveling at 20 mph travels at a speed of 1,760 feet per minute.
At a speed of 1.7 mph, a man will travel 556 feet in approximately 10 minutes.
The fastest thing on Earth besides light and space shuttles is thought to be the tip of a whip, which can reach speeds of over 1,000 mph. Another fast-moving object on Earth is a bullet fired from a firearm, which can travel at speeds exceeding 1,700 mph.

Light in its fastest state in a vacuum only can travel at 3.0*10^8km/s but as it enters the earth's atmosphere, the atmosphere is full of dust particles and layers of gases which can effect the speed of light slightly, in the earths atmosphere light travels at 2.89*10^8 km/s .
No. If something could it would have to move about 700million mph. That's why it is hard to travel to other planets.
It would take approximately 40,238 years to travel 20 light years at 36,000 mph. This calculation takes into account the limitations of current space travel technology and the vast distances involved in interstellar travel.

The speed of light is constant. It is 671,000,000 mph.
To qualify as a hurricane a tropical cyclone must have sustained winds of at least 74 mph. In rare cases, however, hurricane winds can reach nearly 200 mph.
62.14 mph
About 761 mph at sea level.
It's 669,600,000 MPH
About 30-40 mph.
A huge range of speeds from light civilian aircraft at about 100+mph, passenger jets around 500, right up to fighter jets at over 1400 mph
