A section of the railway has a slope of about 0.73. In this section, a vertical change of 1 unit corresponds to a horizontal change of what length?

1/.73 = 1.37

To find the length of the horizontal change corresponding to a vertical change of 1 unit, we need to calculate the slope. The slope is defined as the ratio of the vertical change to the horizontal change.

In this case, the given slope is 0.73. Therefore, for every 1 unit of vertical change, there is a 0.73 unit change horizontally.

So, the length of the horizontal change corresponding to a vertical change of 1 unit is 0.73 units.
