.

Let d be the distance under the question.


"A" family spent    hours for their trip.


"B" family spent    hours for their trip.


Difference in time was 2 hours, according to the condition.


Hence, from the condition, you have this "time" equation


     -  = 2   hours.


To solve it, multiply both sides by 200. You will get


    5d - 4d = 2*200

     d      = 400.


It is your ANSWER :  the distance is  400 miles.

Solved.
