An object travelling at a speed of 1 km/h for an hour would move 1 kilometre.
| 5 km/h | Walking speed |
| 20 km/h | Easy bicycling speed |
| 50 km/h | Residential speed limit Top speed of a running cat, dog or human |
| 80-90 km/h | Speed limit on a major road Top speed of an antelope |
| 110-120 km/h | Highway or motorway speed Top speed of a cheetahThe Cheetah Acinonyx jubatus is an atypical member of the cat family ( Felidae) that hunts by speed rather than by stealth or pack tactics. It is the fastest of all terrestrial animals and can reach speeds of over 110 k m/ h (70 mph) in short bursts. |
| 300 km/h | High-speed trainThis page is about high speed rail in general. There is also the specific British High Speed Train. High-speed rail is public transport by rail with a possible speed above 200 km/h (125 miles per hour). Typically high speed trains travel at top service sp |
| 1000 km/h | AirlinerAn airliner is a type of aircraft initially designed for the transportation of paying passengers. There may be variants developed for air freight, military or luxury corporate use. Occasionally the military version precedes the civilian airliner. Examples cruising speed |
| 1200 km/h | The approximate speed of soundThe speed of sound varies depending on the medium through which the sound waves pass. It is usually quoted in describing properties of substances (e. see the article on sodium). More commonly the term refers to the speed of sound in air. The speed varies (at sea level) |
| 1228 km/h | Current world land speed recordLand Speed Records 1898-2002 The information below is for self-propelled wheeled vehicles travelling over open ground. As such, it does not include records set by vehicles travelling on rails or motorized sleds over frozen lakes. Additionally, the records |
| 26,000 km/h | Re-entry speed of the space shuttle |
| 40,320 km/h | Earth's escape velocityFor the video game title, see Escape Velocity (computer game). In physics, for a given gravitational field and a given position, the escape velocity is the minimum speed an object without propulsion, at that position, needs to have to move away indefinite |
| 1,080,000,000 km/h | Speed of lightCherenkov effect in a "swimming pool" nuclear reactor. The effect is due to electrons moving faster than the speed at which light moves in water. The speed of light (denoted as c reputedly from the Latin celeritas "speed", and also known as Einstein's con |
