Question

A section of a railway has a slope of approximately 0.40. In this section, a vertical change of 1 unit corresponds to a horizontal change of what length? Round your answer to the nearest hundredth.

Answer 1

2.5 units.

Explanation:

The slope = rise / run = 1 / x where x is the horizontal change.

1/x = 0.40

x = 1 / 0.40

= 2.5 units.
