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?

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 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).
Why isn't movement considered the fourth dimension?
Dimensions have units of distance! Movement is a change in distance in time, with units of speed, not distance, so movement is not directly a dimension. However, movement times time is a distance and in that sense movement defines the fourth dimension as r=ct where r is the fourth dimension, a real dimension composed of the speed of light c and time t, r is a distance. The other three dimensions of the Universe are not real dimesnions they are vector dimensions meaning that they are displacements, Ix + Jy + Kz where I,J and K are unit vectors defining directions. Vectors I,J and K have the property that their square is a negative one, I^2 = J^2 = K^2 = -1. A point in four dimensional Universe is p= r + Ix + Jx + Kz = r + V, (r for real and V for vector). Time is expressed in p= ct + Ix + Jy + Kz = ct + V, this point is mathematically called a Quaternion, invented by Willaim Rowan Hamilton in 1843, before the idea of four dimensional spacetime (Einstein, 1905).
How is an inch similar to a centimeter?
They are both measures of distance, with dimension [L]
