Answer:
9.5km
Step-by-step explanation:
To solve this problem, we add the distances given together.
The distance is the sum of the length of path covered. It is a scalar quantity and has only magnitude but no directional attribute.
Distance walked to friend's house = 500m
Distance to mall = 5km
Since 1000m = 1km, 5km will be 5000m
Distance back to house = 4km
In m, this gives 4000m
So;
Total distance covered = 500m + 5000m + 4000m = 9500m
Since 1000m = 1km;
Then, 9500m will given 9.5km
