C Correct answer
Explanation

Ashok's speed is d/6 and Jatin's speed is d/8, where d is the distance. Their difference is 10 km/h, so d/6 - d/8 = 10. This gives d = 240 km.

AI explanation

Let Ashok's speed be x km/h so Jatin's speed is x minus 10 km/h. Using the formula Distance equals Speed multiplied by Time, Ashok covers 6x km and Jatin covers 8 times x minus 10 km for the same distance. Setting them equal gives 6x equals 8x minus 80. Solving for x yields a speed of 40 km/h for Ashok, making the distance 6 times 40 which equals 240 km.
