Light travels at 300 000 km/second
Multiply that by 3600(the number of seconds in an hour)
300 000 x 3 600 = 1 080 000 000
or 1.08 billion miles per hour.
The speed of light is 670,616,628.6 miles per hour (mph).
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.
882km = 548.05 miles.
200 kilometres = 124.27 miles
600 km
The speed of light is 186,000 miles per second.Miles per minute would be 11,160,000.Miles per hour would be 670,616,629.Thats fast!
In a vacuum, the speed of light is always 670,616,629 miles per hour (300,000 kilometers per second). The speed of light changes as it enters a different medium, such as Earth's atmosphere, but the change in speed is essentially negligible.
Light travels at a speed of 186,000 miles per second or 669,600,000 miles per hour. Light travels somewhat slower when it is "in" something, such as glass or water.
miles... in kph??? Anyway, the speed of light is 300,000 kilometers/second; you can convert that to whatever unit you want. For example, to convert to kilometers/hour, multiply by 3600.
Top speeds have ranged from hundreds of miles per hour to speeds far greater than the speed of light.
1 hour = 60 minutes.
Eighty. That is what "miles per hour" means. It means how many miles you will go in one hour, if you keep going at that speed.
