A can give B 70 meters start and C 200 meters start in a kilometer race. How much start can B give C in a kilometer race?
Choose the correct option:
A) 139.78 B) 139.13 C) 139.22 D) 111.0 E) 111.12

Rationale: "a runs 1000 m while b runs 930 m and c runs 800 m . the number of meters that c runs when b runs 1000 m , = ( 1000 * 800 ) / 930 = 860.21 m . b can give c = 1000 - 860.21 = 139.78 m . answer : a"
Answer: A
