It is indeed correct that the statement of the problem is deficient. We have to assume that the two of them start at the same point; otherwise the problem can't be solved. Furthermore, the problem can't ask "at what time" the two of them are 300 miles apart, because the starting time is not given.

Nevertheless, we can still demonstrate the process for solving the problem....

After t hours, the distance between them (from the Pythagorean Theorem) is

The number of hours after they start that the distance between them is 300 miles is

= 3.8411 to a few decimal places

To the nearest minute, that is 3 hours and 50 minutes.
