1 light-hour = 1.07925285 × 109 kilometers.
299,792.458
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.
Depends what method of transportation I am using.
The speed of light in a vacuum is about 300,000 kilometers per second. So, in one second, light would travel 300,000 kilometers.
460
If 1 hour ===> 40 km, then 2 hours ===> 80 km.
That depends at what speed you are travelling.
One lightyear is equivalent to 9.461 trillion kilometers. To find the distance in kilometers per hour, you would need to divide this by the number of hours in a year (8,760 hours). This would give you approximately 1,080,815,900 kilometers in one lightyear per hour.
120 mph = 193.12 km/h
At one kilometer an hour 377 hours.
One one year's time, light can travel 9.4605284 × 1012 kilometers.
