A Correct answer
Explanation

Average speed = Total distance / Total time. Total distance = 50 + 40 = 90 km. Total time = 1 + 1 = 2 hours. Average speed = 90 / 2 = 45 km/hr.

AI explanation

The average speed is calculated using the total distance divided by the total time. The total distance is 50 km plus 40 km, which equals 90 km, and the total time is 1 hour plus 1 hour, which equals 2 hours. Dividing 90 km by 2 hours gives an average speed of 45 km/hr.
