Answer...
The speed of a moving body is the distance travelled by it in unit time. If the distance is in km and time is in hours, then the speed is km/hr.
Answer:
The listed answers are what they call Newtonian Physics - meaning that they are non-relativistic. They do not take into consideration traveling fast enough to induce Relativity to any noticeable extent.
Once you begin to introduce speeds approaching the speed of light, then time and distance change in their relationships depending on your perspective. Einstein's equations showed that time is not a constant across all observers as it is in Newtonian Physics. Speed is also capped at the speed of light in a vacuum and therefore is not additive in the usual manner. It all gets very complicated and very non-intuitive.
The take-away is that the D=RT formulas work for everything we would normally encounter in our lives but when you begin to look at cosmology or space travel - even just orbiting space stations and satellites, you have to switch to a different set of time-speed-distance formulas.
