The question is:

WHile on a straight road, car X and Y are travelling at different constant rates. If car X is now 1 mile ahead of car Y, how many minutes from now will car X be 2 miles ahead of Car Y?

1. car X is travelling at 50 mph and car Y is travelling at 40 mph

2. 3 minutes ago, car X was 1/2 mile ahead of car Y.

My problem is, while it makes logical sense in my head that both will be individually be enough to answer the question, I am not sure, because I can not reach the answer using the second statement.

Couldl somebody please help explain it to me.
