Aadya and Ethan like playing with remote-control cars. There's a straight track at the
park that is 500 yards long. Aadya's car started at one end of the track and got 405
yards before its battery ran out. Ethan's car started at the other end of the track and
traveled 10 more yards than Aadya's car before its battery ran out. What is the
distance between the two cars now if they did not collide?
