Two stations A and B are 660 km apart. A train T1, which stops for 7 minutes at every town-station and for 3 minutes at every
village-station, started from A with a speed of 40 km/hr towards B and at the same time a train T2 with a speed of 60 km/hr, which
does not stop at any intermediate station, started from B towards A. They cross each other at C which is 420 km away from B. If the
