A can give B 100 meters start and C 120 meters start in a kilometer race. How much start can B give C in a kilometer race?	Choose the correct answer
A) 10.22 meters
B) 11.22 meters
C) 22.22 meters
D) 33.22 meters
E) none of these

Rationale: "explanation : a runs 1000 meters while b runs 900 meters and c runs 880 meters . therefore , b runs 900 meters while c runs 880 meters . so , the number of meters that c runs when b runs 1000 meters = ( 1000 x 880 ) / 900 = 977.778 meters thus , b can give c ( 1000 - 977.77 ) = 22.22 meters start answer : c"
Answer: C
