A Correct answer
Explanation

Distance = Speed * Time = 40 km/hr * 9 hours = 360 km. New time = Distance / New Speed = 360 km / 60 km/hr = 6 hours.

AI explanation

First, calculate the total distance of the journey using Distance = Speed * Time, which gives 40 * 9 = 360 km. To find the new time, divide this distance by the new speed, yielding 360 / 60 = 6 hours. It will take 6 hours to travel the same distance.
