Identify the given values and operation

\[

$$\begin{aligned} &\text{Train distance} = 6.036\text{ km}\\ &\text{Bus distance} = 1.9\text{ km}\\ &\text{Total distance} = \text{Train distance} + \text{Bus distance} \end{aligned}$$

\]

Perform decimal addition

\[

$$\begin{aligned} 6.036 + 1.9 &= 6.036 + 1.900\\ &= 7.936 \end{aligned}$$

\]
