D Correct answer
Explanation

Perimeter = 2*(200+100) = 600 m. 5 rounds = 3000 m = 3 km. Time = Distance/Speed = 3 km / 5 km/hr = 0.6 hours = 36 minutes.

AI explanation

The perimeter of the rectangular plot is 2 times the sum of its length and breadth, so the perimeter is 2 times (200 m plus 100 m) which equals 600 m. For 5 rounds, the total distance to be covered is 5 multiplied by 600 m, which equals 3000 m or 3 km. At a speed of 5 km/hr, the time taken is distance divided by speed, so 3 km divided by 5 km/hr equals 0.6 hours. Converting this to minutes by multiplying by 60 gives 36 minutes.
