2.8 km/h
10 km
10.5 km
11 km

Explanation:

Step1: Calculate distance to friend's house and back

The distance to the friend's house is 0.5 km and the return - trip distance is also 0.5 km. So the total distance for this part is $0.5 + 0.5=1$ km.

Step2: Add distance to the mall

The distance to the mall is 10 km. Add this to the previous distance. The total distance traveled is $1 + 10=11$ km.

Answer:

11 km
