Points A and B are 150 km apart. Cars 1 and 2 travel from A to B, but car 2 starts from A when car 1 is already 20 km away from A. Each car travels at a speed of 100 kmph for the ﬁrst 50 km, at 50 kmph for the next 50 km, and at 25 kmph for the last 50 km. The distance, in km, between car 2 and B when car 1 reaches B is (TITA )?

Solution:
Time taken by Car 1 to travel first 20 km =20/100 hr =1/5 hr
Thus Car 2 will reach B 12 minutes after Car 1 will reach.
Thus Required distance = time×speed=1/5×25=5 km
