centimeters
A stopwatch or a measuring tape can be used to measure the speed of a snail. You would time how long it takes the snail to travel a specific distance, or measure the distance the snail travels in a set amount of time.
33,055m or 33.055Km
30,000 metres or 30km
The Unit Used To Measure A Train Can Be Kilometer.
A train that travels at 40 kilometers per hour (kph) for 10 hours goes 400 kilometers. If the train goes 50 kph for 8 hours, it also travels the same 400 kilometers. The difference in speeds is 10 kph, and the difference in times is 2 hours.
you would measure it with feet
Light years is a measure of distance, not of time; it is the distance that light travels in one year.
Meters
Impossibly long: if you did manage to get a car inside a train, it would only be in a special carriage where you would not be able to drive any significant distance. More seriously, though, the journey time will depend on the speed at which the train travels and that can range from around 350 mph down to less than 10 mph!
A beam of light travels at a speed of 299,792 kilometers per second. In one year, it would cover a distance of approximately 9.46 trillion kilometers (5.88 trillion miles). This distance is known as a light-year, a unit commonly used in astronomy to measure vast distances in space.
A light year is a measure of distance not time. A light year is the distance light travels in one year. So for light to travel 6,300 light years, would take 6,300 years
