Solution

Basically, we are given


speed=210.0\operatorname{km}hr^(-1)
dis\tan ce=5.9*10^9\operatorname{km}

We want to find the time

Recall that


speed=\frac{\text{distance}}{\text{time}}

We will make time the subject of formula


time=\frac{\text{distance}}{\text{speed}}

We therefore find the time using the data above


\begin{gathered} time=\frac{\text{distance}}{\text{speed}} \\ time=(5.9*10^9)/(210) \\ time=28095238.1\text{hours} \end{gathered}

Therefore, it would take 28095238.1 hours
