Answer:

average speed = total distance / total time

Here, we know that one-way distance = 224 km

Hence total distance/two-way distance is equal to 224 km × 2

= 448 km

Total time = 2.5 hours + 3 hours

= 5.5 hours

Now, we just have add the values to the formula

Average speed = 448 / 5.5

≈ 81.45 km/h
