from the question given, we have some variables

$\begin{gathered} \text{speed}=1.9*10^5\operatorname{km}\text{ /s} \\ \text{time}=6.4*10^5s \\ \text{distance}=x \end{gathered}$

now the formula for speed is given as

$\begin{gathered} \text{speed}=\frac{\text{distance}}{\text{time}} \\ 1.9*10^5=(x)/(6.4*10^5) \\ x=(1.9*10^5)*(6.4*10^5) \\ x=1.22*10^(11)\operatorname{km} \end{gathered}$
