C Correct answer
Explanation

The time taken to cover 100 km at 20 km/hr is 100/20 = 5 hours. In the same 5 hours, at a speed of 50 km/hr, the distance covered is 50 * 5 = 250 km.

AI explanation

First, calculate the time taken by dividing the distance by the speed, which gives 100 km divided by 20 km/hr, equaling 5 hours. Using the formula Distance = Speed x Time, multiply the new speed of 50 km/hr by this same time of 5 hours. The new distance covered is 250 km.
