Murali travelled from city A to city B at a speed of 4 kmph and from city B to city C at 6 kmph. What is the average speed of Murali from A to C given that the ratio of distances between A to B and B to C is 2 : 3?
A. 48 kmph Select the correct option: A) 33 B) 5 C) 28 D) 7 E) 16
Let the distances between city A to B and B to C be 2x km and 3x km respectively.   Total time taken to cover from A to C   = (2x)/4 + (3x)/6 = (6x + 6x)/12 = 12x/12 = x Average speed = (2x + 3x)/(x) = 5 kmph.   Answer: 5
