Question

4. Indicate the following by using integers:
(a) 3 km towards south​

Answer 1

Answer:

We know that moving 10 m towards North is represented by +10 and also, −10 represents moving 10 m towards South, which is opposite direction of North.



If a positive (+ve) integer indicates a particular direction; then the negative (-ve) integer indicates the opposite direction and vice versa.

Hence, from the above graph of directions we conclude that integer used to represent walking 3 km towards the north is +3 km.
