If spacetime is 3 dimension of space and one of time why can't time be also a distance and the perception of change be really the expansion of the universe?

You almost correctly solved the problem of Space.
"Space" is three vectors dimension of space (ix +jy +kz) and one scalar dimension of space (r). Hamilton defined Quaternions in 1843. Einstein was correct in calling for a 4 dimesnional space, but Einstein's Spacetime is an incorrect 4 dimensional space both Physics-wise and mathematically.
Einstein and others considered time an imaginary (vector) dimension ( it) and space three real dimensions (x,y,z). This is opposite to reality where space is quaternion with one real scalar dimension (r) and three vector dimensions (ix +jy+ kz). The real dimension r is related to time by r=ct where c is the speed of light.
In summary Space is 4 dimensional and all dimensions are space one real space (r=ct) and three vector spaces (ix +jy +kz), just as you proposed,
why can't time be also a distance?
It can and it is called Quaternion Space.

What is dimension of power?
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
What are dimensions for long jump?
The only dimension is length (or distance).
How do you calculate the distance between the center of cube and its vertices in 3 dimension?
By using Pythagoras' theorem.
What dimension is circumference?
the enclosing boundary of a curved geometric figure, esp. a circle. the distance around a circle
Weight x distance divided by time?
Weight has same dimension and unit as force. Distance has same dimension and unit as displacement. So weight * distance has same dimension and unit as force * displacement. Force * displacement is work done by the force. Work divided by time to do the work is Power. So weight * distance divided by time also has same dimension and unit as Power although it is not power. S.I. unit of weight * distance divided by time is Newton *meter/second or Nms-1 (in abbr.) It's dimensions are 1, 2, -3 in mass, length and time respectively. Note that given quantity's unit can't be joule/second or watt because weight * distance is not work done, only unit and dimension are same1 . 1. Two physical quantities may have same dimensions and units but that doesn't mean they refer to same quantity.
Perception distance plus reaction distance plus braking distance is called?
Stopping Sight Distance
If an inch and a second are both linear measurements one being a distance of either the first second or third dimension the other being of the fourth which is less?
An inch, being a measure of length in the first, second, or third dimension, is less than a second which is a measure of time in the fourth dimension. Time is considered the fourth dimension in the context of spacetime, where events are viewed as occurring in a continuum made up of three spatial dimensions and one temporal dimension.
How can the proposed expansion of space itself account for distance or velocity of galaxies wouldn't space expand in every dimension leaving proportions the same?
yes, but they don't know that space actually expands though it probably does.
What is dimension of power?
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
What is the distance a vehicle travels from the moment an event occurs until the driver sees it and becomes aware of the danger?
If you experience brake failure while driving you should turn off the engine and coast to a complete stop?
What three things add up total stopping distance?
Perception Distance + Reaction Distance+ Braking Distance.
What three things add up to total stop distance?
Perception Distance + Reaction Distance+ Braking Distance.
What tree things add up to total stopping distance?
Perception Distance, Reaction Distance and Braking Distance
What is Perception distance plus reaction distance plus braking distance is called?
Perception distance plus reaction distance plus braking distance is called total stopping distance. It represents the total distance a vehicle will travel from the moment a driver recognizes a hazard until the vehicle comes to a complete stop.
What is hallucinoges?
Substances that distance the perception of objective reality.
The distance your vehicle travels while you respond to a road hazard is called?
perception distance.
What are dimensions for long jump?
The only dimension is length (or distance).
