B Correct answer
Explanation

Relative speed = 50 - 40 = 10 km/hr. Time = Distance / Relative Speed = 30 / 10 = 3 hours.

AI explanation

Using the concept of relative speed, Thakur's effective speed is 50 km/hr minus 40 km/hr, which equals 10 km/hr. To get 30 kms ahead, the time required is 30 kms divided by 10 km/hr, giving exactly 3 hours. Thakur will be 30 kms ahead in 3 hours.
