2. Two cars A and Bare placed at 100 km from each other. If they start running simultaneously towards each other, they meet after 1 h. If they start running simultaneously in the same direction with car ‘A’ running towards car ‘B, the distance between them after 1 h becomes 80 km. What is the speed of car ‘A’ in km/h?
(a) 40
(b) 80
(c) 60
(d) Data inadequate

3. A passenger train running at the speed of 80 km/h leaves the railway station 6 h after a goods train leaves and overtakes it in 4 h. The speed of the goods train is
(a) 32 km/h
(b) 40 km/h
(c) 50 km/h
(d) 60 km/h

4. Two persons A and B are at two places P and Q respectively. A walks at v km/h and B is 2 km/h faster than A, starting simultaneously from where they stand. If they walk towards each other, they meet in 72 min. If they walk in the same direction, the faster overtakes the slower in 6 h. Find their respective speeds (in km/h).
(a) 3 and 5
(b) 4 and 6
(c) 2½ and 4½
(d) 3½ and 5½
