B Correct answer
Explanation

Average speed is total distance divided by total time. Total distance = 6 km + 8 km = 14 km. Total time = 2 hours + 2 hours = 4 hours. Average speed = 14 / 4 = 3.5 km per hour.

AI explanation

Using the formula for average speed, which is total distance divided by total time, we add the individual distances to find the total distance. The total distance is 6 km plus 8 km, which equals 14 km, and the total time is 4 hours. Dividing 14 km by 4 hours gives an average speed of 3.5 km per hour.
