You need to begin by converting the given information to the same units.
In other words, you need to either convert 70.22 km/s to miles-per-hour OR you need to convert 384,000 miles to kilometers.
Next, substitute your values for distance and rate into the famous formula: \(\displaystyle \text{DISTANCE} = \text{RATE} \times \text{TIME}\) and solve for time.
The last step is to break-down the decimal number of hours into hours + minutes + time.
Now that you have the steps, what is your very next question?
