Correct Answer: 515
Solution : Given that Anil and Arun are running in the same direction with the speed of 72 km/hr and 90 km/hr respectively. Length of circular track = 2575 m Relative Speed of Anil and Arun = 90 – 72 = 18 km/h = 18$\times\frac{5}{18} = 5$ m/s ⇒ Time taken by them to meet for the first time on the track while running in the same direction = $\frac{\text{Length of track}}{\text{Relative speed in same direction}}$ ⇒ $\frac{2575}{5}$ = 515 seconds Hence, the correct answer is 515.
