Respuesta :
Here, we are required to determine the total distance travelled.
- The total distance travelled is; 11km.
According to the question, the first phase of the travel involves walking 0.5km to a friend's house and returning back home.
The distance travelled in the first phase of the travel is the sum of distance covered to and from the friend's house.
Therefore, we have; 0.5km + 0.5km
i.e 1km.
Afterwards, the second phase of the travel involves travelling by car to the mall which is 10km away. This is a one-way travel as there's no indication of a trip back home;
Therefore, the total distance travelled is;
10km + 1km = 11km
