The runner's speed is 3 kilometers per 30 minutes. In somewhat more familiar units, it's also 6 km per hour.

It's speed - which is 90 Km/h

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

36 minutes. But, no bird on earth can fly at 500 km per hour.

The speed is the distance traveled divided by the time it takes to travel that distance. In this case we with divide 8 kilometers by 10 minutes to get 0.8 km/minute. One hour is sixty minutes, so this works out to 48 km/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

If this jet keeps a constant speed of 60 kilometers every 5 minutes throughout the entire 6 hours of it's flight, it will travel 4,320 kilometers. Distance = Speed * Time Speed = 60 km / 5 min ( 60 km/ 5 min ) * ( 60 min / 1 hour ) = 720 km / hour Distance = ( 720 km / hour ) * ( 6 hours ) Distance = 4320 km

speed of light

Just as fast as light travels anywhere else; the speed of light in a vacuum is constant - about 300,000 kilometers per second. If you refer to the time, you can divide the distance (about 150 million kilometers) by the speed; after converting to minutes, in this case the result is about 8 minutes and 20 seconds.

30 kilometers per hour.
