The speed of light is 2.99793x108 m/s, which, when multiplied by the number of seconds in an hour (3600) and divided by the number of metres in a km comes to 1,079,254,800 km / hr - a little under the closest that the Planet Saturn approaches the Earth.
A more interesting way to remember the speed of light is to recall that it is approximately 1 foot per nanosecond.
Light is so fast that it is usually expressed as about 300,000 kilometers per second. If you multiply that by 3600 seconds / hour, you get the speed in kilometers per hour.
Speed of light in vacuum = 1 079 252 848.8 km per hour
About 186,000 miles per hour or 300,000 kilometers per hour.
How fast is 60 kilometers per hour?
55 kilometers is very fast for one hour. 88.51 kilometers per hour = 55 miles per hour. Wow that is really fast. Imagine driving that fast.
