Identify the given values and operation

\[

$$\begin{aligned} &\text{Train distance} = 614.3\text{ km} \\ &\text{Bus distance} = 554.6\text{ km} \\ &\text{Total distance} = \text{Train distance} + \text{Bus distance} \end{aligned}$$

\]

Calculate the sum of the decimals

\[

$$\begin{aligned} 614.3 + 554.6 &= (614 + 554) + (0.3 + 0.6) \\ &= 1168 + 0.9 \\ &= 1168.9 \end{aligned}$$

\]
