Question

In a race of 600 m, a can beat b by 60 m and in a race of 500 m/ b beat c by 50 m. by how many m will a beat c in race of 400

Answer 1

As we can see, the distance between any pair(a and b or b and c) is always distance of race / 10. So in 400 m race distance between a and b is

400 m / 10

= 40 m

distance between b and c is

400 m / 10

= 40 m

So, the total distance between a and c is

40 m + 40 m

= 80 m

ANSWER : a beats c by 80 m
