A Correct answer
Explanation

Speed = Distance / Time. Distance = 60 km, Time = 40 minutes = 40/60 hours = 2/3 hours. Speed = 60 / (2/3) = 60 * 3 / 2 = 90 km/hr.

AI explanation

To use the formula Speed = Distance / Time in km/hr, first convert the time of 40 minutes into hours by dividing by 60, resulting in 2/3 hours. Next, divide the distance of 60 km by 2/3 hours. This gives a speed of 90 km/hr.
