Question

In a km race, a beats b by 200m and c by 280 m. by what distance will b beat c in the race

Answer 1

See attached diagram.

Distance between A and B = 200 m

Distance between A and C = 280 m

Find the distance between B and C:

Distance = 280 - 200 = 80 m    

Answer: B beats C in the race by 80 m

Answer 2

The given conditions are a beats b by 200m and c by 280 m in a km race.  

After that, we need to calculate the distance that b wins in the race.  

The calculate is given below. We can take A: B = 1000: 200 and A: C = 1000: 280.

It is further expanded properly. And, we can find out the answer as 520m.
