Over two laps of a 400 m track, Rani runs the first lap at 8 m/s and the second at 5 m/s, while Sita runs the whole way at 6.4 m/s. What is the result?

Question

Accepted Answer

Sita by 5 s. Rani: 50+80=130 s. Sita: 800/6.4=125 s. Sita wins by 5 s. (Averaging 8 and 5 to 6.5 m/s wrongly makes Rani win.)
