In racing over a given distance d at uniform speed, A can beat B by 20 meters, B can beat C by 6 meters, and A can beat C by 23 meters. What is the distance d in meters?	Choose the correct choice from the following answers:
A) 32
B) 36
C) 40
D) 48
E) 60
When A is at the finish line, B is 20 meters back, and C is 23 meters back.   When B runs another 20 meters to the finish line, C is 6 meters back.   So B gains 3 meters every 20 meters covered.   To gain a final difference of 6 meters, B runs a total of 40 meters.   The answer is 40.
