Since these are all distance/speed, then yes.
The speed of the train is 42.5 kilometers per hour.
Its speed is 120 kilometers per hour.
Average speed in kilometers per hour is 500/10 or 50.
-- negative average acceleration -- fatigue
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 kilometers per hour is 299 000 kilometers per second X 60 gives you kilometers per minute X 60 gives you kilometers per hour.
"Light-year" is not a speed, it is a distance - the distance light travels in a year.The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
The speed of light in a vacuum is approximately 299,792 kilometers per second.
Speed of light is 300,000 kilometers per second. Multiply that by 3600 to convert that to km/hour.
Speed of light in vacuum = 1 079 252 848.8 km per hour
Since these are all distance/speed, then yes.
75 kilometers is not a speed, it is a distance. A speed might be 75 kilometers per hour, 75 kilometers per day, or 75 kilometers per second.75 kilometers is not a speed, it is a distance. A speed might be 75 kilometers per hour, 75 kilometers per day, or 75 kilometers per second.75 kilometers is not a speed, it is a distance. A speed might be 75 kilometers per hour, 75 kilometers per day, or 75 kilometers per second.75 kilometers is not a speed, it is a distance. A speed might be 75 kilometers per hour, 75 kilometers per day, or 75 kilometers per second.
The speed of light in a vacuum is 186,282.397 miles per second or 670,616,629.2 miles per hour.
No, sound and light travel at different speeds. In a vacuum, light travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second), while the speed of sound in air is around 767 miles per hour (1,235 kilometers per hour).
The speed of light in a vacuum is 300.000 kilometers per second, that's 671.000.000 miles per hour.
That's 300,000,000 (three hundred million) kilometers per hour. For comparison, an approximation of the speed of light is 1,080,000,000 kilometers per hour (300,000 kilometers per second).
