C) 50
D) 60
E) 70
When A is at the finish line, B is 10 meters back, and C is 14 meters back.   When B runs another 10 meters to the finish line, C is 6 meters back.   So B gains 2 meters every 10 meters covered.   To gain a final difference of 6 meters, B runs a total of 30 meters.   The answer is 30.
