Solution

The distance covered is the length of the entire route. This

distance is given by the perimeter of the route.
FOR ONLINE READING ONLY
Perimeter of the route = distance from home to school + distance
from school to the market + distance from the market to home

= + 3 km + 2 km 1 km

= 6 km

Therefore, the pupil covered a distance of 6 km.
