Murali travelled from city A to city B at a speed of 20 kmph and from city B to city C at 80 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?
Choose the correct choice from the following:
A) kmph  B) kmph  C) kmph  D) kmph  E) kmph
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)/20 + (3x)/80   = (8x + 3x)/80 = 11x/80   = (2x + 3x)/(11x/80) = 36.4 kmph.   Answer: kmph
