Problem for an 8 years old child

Logic Level 2

There are two cars A and B.

A is going from Madrid to Seville by the M-232 road, A leaves Madrid at 9:00 am and takes an average speed between 50 km/hour and 150 km/hour.

B is going from Seville to Madrid by the same road M-232, B leaves Seville at 10:00 am and takes an average speed between 75kms/hour and 125 km/hour.

When the two cars cross each other, what car will be closer to Sevilla?

Details and assumptions:

From Madrid to Seville are 500 kms.

Cars are considered points in space massless (without mass) and the road is unidimensional

Impossible to tell Both cars are to equal distance to Seville A B

It's very simple, when the two cars cross each other they are to equal distance to Seville and Madrid( they are crossing each other), it doesn't matter(mind) the speed...

The ratio of the speeds given is just enough to deduce the answer. Didn't take more than 2 seconds!(except for the reading part!)
