C Correct answer
Explanation

Total distance = 30 km. Half distance = 15 km. Time 1 = 15/50 = 0.3 hours. Time 2 = 15/20 = 0.75 hours. Total time = 0.3 + 0.75 = 1.05 hours.

AI explanation

Mohak covers the first 15 km at 50 km/h, which takes 0.3 hours using the formula Time equals Distance divided by Speed. He covers the remaining 15 km at 20 km/h, which takes 0.75 hours. The total time taken is 0.3 plus 0.75, which equals 1.05 hours.
