ATQ,
When Tanya runs 800 metres, Ravi runs (800 – 160 = 640 metres)
When Tanya runs 800 metres, Sumit runs (800 – 240 = 560 metres)
So, the ratio of the distance covered by Tanya, Ravi, and Sumit when Tanya runs 800 metres respectively:
= 800:640:560 = 20:16:14
Distance covered by Sumit when Ravi completes 800 m = (800/16) × 14 = 700 metres
Therefore, Ravi beats Sumit by (800 – 700 = 100 metres)
