Slovak broad track

We used to learn in school that Ukrainian railways have wider tracks than ours because of less stable ground. In reality, the track gauge is a deliberate design choice.

Calculate how many millimetres our standard gauge of 1,435 mm differs from the Ukrainian gauge of 1,520 mm.

By what percentage does our standard gauge differ from the Ukrainian gauge?

Final Answer:

x =  85 mm
p =  5.6 %

Step-by-step explanation:

$$\begin{gathered} a=1520\text{mm} \\ b=1435\text{mm} \\ x=a-b=1520-1435=85\text{mm} \end{gathered}$$

$p=100\cdot \frac{x}{a}=100\cdot \frac{85}{1520}=\frac{100\cdot 85}{1520}=\frac{8500}{1520}=5.6\%$
