<em>The average speed is 22.2 km/h</em>
Explanation:
<u>Average Speed</u>
Given an object travels a total distance d and took a total time t, then the average speed is:

The mailman first drives d1=7 km at v1=15 km/h. The time taken to drive is:

Then he drives d2=7 km at v2=43 km/h taking a time of:

The total time is
t=0.467 h + 0.163 h = 0.63 h
The total distance is
d = 7 km + 7 km = 14 km
The average speed is:

The average speed is 22.2 km/h
