Question

Rajesh goes 18 km north from a point A, then he goes 30 km south along the same road. If the distance towards north is represented by a positive integer then how will you represent the distance travelled towards south? What will be Rajesh's final position represented as?

Answer 1

Final position 30 km

Answer 2

The distance travelled towards South will be represented as a negative integer.

So, Rajesh's final position will be represented as 18 km - 30 km = - 12 km
