Not enough information.
We have no idea in which direction either car is going.
Are they going opposite directions? The same direction? perpendicular directions?
Your response stated that they are going in the same direction.
The faster car is going 15 mph faster than the slower car.
so in 20 minutes (1/3*15) will have gone 5 miles further.
