No, the speed of light has remained constant over time according to current scientific understanding.
Speed and position are related in that speed is the rate at which an object changes its position over time. The greater the speed of an object, the faster it changes its position. The position of an object at any given time can be calculated by integrating the speed over time.
At the speed of light, time does not exist as we understand it. According to Einstein's theory of relativity, time slows down as an object approaches the speed of light, eventually coming to a stop at the speed of light. This means that for light itself, time does not pass.
Yes, the hippo changed its speed. We can tell because the rate of change in the hippo's position over time is not constant, indicating a change in speed.
A laser speed gun emits a pulse of light towards a moving vehicle. By measuring the time it takes for the light to hit the vehicle and bounce back, the speed gun can calculate the speed of the car based on the change in distance over time.
speed How fast in which direction is velocity.
this can never change, light travels at a constant speed, a light year is the distance light travels in one year.
Time does not affect speed. Measures of speed may be changed over different time periods but that is not the same thing.
In Einstein's paper about the relation of mass to energy, the speed of light appears in two different roles. Ellis and Uzan point out that the speed of light plays multiple roles in physical equations generally, and analyze the significance of this in relation to recent proposals that the speed of light may have changed over time.

The laws of physics have not changed over time. Our understanding of them has changed over time.

from a purely mathematical stand point, if something were to reach the speed of light the time dialation/length contraction formula would yield something over 0. This is beacuse the formula is: constant/[(1-(velocity/speed of light)^2] as you can see, if velocity=speed of light, you get something over zero.
