A --------------------------B ------------------------------ C
In the forward journey Ron went from A to C through B as shown. Distance between A and B is “d” miles which he travelled at a constant speed of “x” miles per hour. Distance between B and C is “2d” miles which he travelled at a constant speed of “2x” miles per hour.
In the backward journey Ron went from C to A through B. While travelling from C to B in the backward jouney he travelled at a constant speed of 3x/2 miles per hour. From B to A in the backward journey he travelled at 2x miles per hour. Thereby completing a round trip.
A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.

Average Speed = Total Distance travelled/Total time taken
Forward Journey = 3d/(d/x + 2d/2x) = 3/(2/x) = 1.5x
Backward Journey = 3d/(d/2x + 2d/(3x/2)) = 3x/(1/2 + 4/3) = 18x/11 = 1.6x
B > A
Forward Journey = 3d/(d/x + 2d/2x) = 3/(2/x) = 1.5x
Backward Journey = 3d/(d/2x + 2d/(3x/2)) = 3x/(1/2 + 4/3) = 18x/11 = 1.6x
B > A
