D Correct answer
Explanation

Let time be t. Distances are 70t and 90t. 90t - 70t = 350 => 20t = 350 => t = 17.5 hours. Total distance = 70t + 90t = 160t = 160 * 17.5 = 2800 km.

AI explanation

Since the trains travel for the same amount of time until they meet, the difference in distance is 90t - 70t = 350, yielding a travel time of t = 17.5 hours. The total distance between Kanpur and Agra is their combined speed multiplied by this time, calculated as (70 + 90) * 17.5 = 2800 km.
