Answer :
The boy travelled 3 km north and 4km east.
(A) the total distance travelled = 3+4 = 7km
(B) the shortest distance is through the path joining the starting and ending point.
it will be √4²+3² = √9+16 = √25 = 5km
(C) the displacement is the shortest distance joining the starting and ending point. So it is 5km

1) the distance traveled =7 km
2) the minimum distance = 5 km
3) we know that the shortest distance is called as displacement and it is the definition for displacement therefore,the displacement=5 km
