1.	5. A bus moves from stop ‘A to stop 'B' with a speed of 40 km/hr and then from stop 'B' to stop 'Awith a speed of 50 km/hr. Its average speed is(a) 48.5 km/hr (b) 44 km/hr (c) 45 km/hr (d) 44.4 km/hr
Answer» Answer: It’s true, without telling us how long it took to travel from A to B at 30 kmph, there’s no way of telling how far AWAY it is. Seems like someone may be trying to trick you. The second speed GIVEN is also irrelevant, as the distance from A to B is the same as the distance from B to A. In that sense you could say the distance traveled by the CAR is 2 x the distance from A to B. If you look at the situation in a DIFFERENT way, then the distance traveled by the car is 0 km, miles, inches…whatever. Because the car ENDS at its point of origin, the distance traveled from start to finish is nothing.
