How long does it take to drive 848 miles?
This cannot be answered properly without knowing what your speed is.
Since Einstein gave us the theory of relativity, and it states that time is an extension of space, it would be 848. 848 what, you ask? Since you used miles, it would be 848 miles. Read about the theory and you will start to understand that time and space are so closely related, (you can't have one without the other), they are in fact, the same.
