D Correct answer
Explanation

Distance = Speed * Time. Distance = 30 km/hr * 6.2 hours = 186 km. Time for train = 186 km / 24 km/hr = 7.75 hours. 7.75 hours is 7 hours and 45 minutes.

AI explanation

Using Distance = Speed multiplied by Time, the distance to the destination is 30 km/hr multiplied by 6.2 hours, which equals 186 km. The time taken by the second friend traveling by train is 186 km divided by 24 km/hr, which equals 7.75 hours. Since 0.75 hours equals 45 minutes, the time of reaching is 7.45 hours.
