In a 924-m race, Anil reaches the final point in 35 s and Pawan reaches the final point in 66 s. By how much distance does Anil beat Pawan?
Answer: D
Anil beats Pawan by 434 m. Pawan's speed is 924/66 = 14 m/s. In the 35 seconds Anil takes, Pawan covers 14 x 35 = 490 m, so he is 924 - 490 = 434 m behind when Anil finishes. 431, 432 and 433 m do not follow from these speeds. Anil's speed is 924/35 = 26.4 m/s. The distance is the same, so the time ratio (35 : 66) is the inverse of the speed ratio. Alternatively, Pawan runs 35/66 of the race in Anil's time, which is 924 x 35/66 = 490 m.
