It is way easier than that. Car B will take 60 minutes to catch up with car A, because it is going 1 mph faster. The absolute speed of each car does not matter, only the relative speed. Car B will also go 51 miles in that 60 minutes, because that is how fast he is going. Car A will go 50 miles, because he started 1 mile ahead of car B. No need for any equations or anything.
