Sean Carroll has a really great video on this. If you don’t feel like sitting through an hour, search for Minkowski Diagrams.
Lets think about a standard 2-D graph. Along the vertical axis you have time, along the horizontal axis you have distance.
You can draw a line through any two points on this graph.
That line will represent the relationship between space and time, also called velocity.
The greater the angle of the the line, the greater the velocity, the faster you move through the time axis. The lower the angle of the line the lower the velocity, the more you move through space and less through time.
It’s not the most intuitive thing, but I hope this helps.
