a can give b 300 meters start and c 600 meters start in a kilometer race . how much start can b give c in a kilometer race ?
"a runs 1000 m while b runs 700 m and c runs 400 m . the number of meters that c runs when b runs 1000 m , = ( 1000 * 400 ) / 700 = 571.43 m . b can give c = 1000 - 571.43 = 428.57 m . answer : c"
