Question

In 1km race A gives B a start of 100m and in 1km race B gives C a start of 80m. In a 1km race who will win and by how much distance from the worst performer between the two losers?

Answer 1

Answer:

Ratio of speeds of A:B = 1000:900 = 100:90

Ratio of speeds of B:C = 1000:920 = 100:92

Therefore, when A moves 1000m , B moves 900 m and when B moves 900m, C moves 828m

Since , C moves 8 % less than B in the same time . Thus, C is the worst performer and A will win by him by 172 m
