In a race of 1000 m, A can beat by 100 m, in a race of 800m, B can beat C by 100m. By how many meters will A beat C in a race of 1000 m?
Choose the correct choice from the following:  A) 122.9 m  B) 127.5 m.  C) 122.2 m  D) 222.9 m  E) 212.5 m
When A runs 1000 m, B runs 900 m and when B runs 800 m, C runs 700 m.   When B runs 900 m, distance that C runs = (900 * 700)/800   = 6300/8=
