10 kilometers per hour
Hint: 10000 meters = 10 km, 30 minutes = ½ hour... 10,000 meters in 30 minutes = 10 kilometers per 0.5 hour = 20 kilometers 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).
The speed of each meter per second is the same as 3.6 kilometers per hour. As an example, 10 meters per second is 36 kilometers per hour.
It is a measure of speed, and means that if such a speed is maintained, the object will move 10 kilometers every hour.
10 kilometers per hour
10 miles per hour is equal to approximately 16.09 kilometers per hour.
Average speed in kilometers per hour is 500/10 or 50.
