Here's why:
* Speed is the rate at which an object changes its position. It's calculated by dividing the distance traveled by the time it takes.
* Mass is the amount of matter in an object. It doesn't directly affect speed.
To find the speed, you need to tell me how far the 1 kilogram mass travels in one hour.
For example:
* If the mass travels 10 kilometers in one hour, its speed is 10 kilometers per hour.
* If the mass travels 100 meters in one hour, its speed is 100 meters per hour.
Let me know the distance, and I can calculate the speed for you!
