The distance on maps is measured by the little scale that is located in the bottom right corner of the map in this case. I can not measure it precisely over a picture like this but I would say that between London and Ashby on this map there is 100 miles of distance, and between London and Exeter there is around 150 miles of distance. This is measured by using a ruler and applying the distance that is on the scale to the distance in inches on the ruler.

If we start to travel from the Mississippi River westwards to the Pacific Coast, than the starting point is a lowland, vast one, as we continue to go towards the west we will encounter high mountains, the Rocky Mountains more specifically, and the elevation will go up to 4,400 meters above sea level, than we will go down, elevation wise, to the high plateaus and will be on elevations between 1,000 and 2,000 meters, and after we go up again to almost 4,400 meters as we cross the Cascade Mountains. After the Cascades we go gradually downwards towards the lowlands, where we will first go a bit bellow sea level, and than little up in the lowlands along the Pacific Coast, and at the end reach a point of zero elevation.
