Question

Rita goes 20 km towards east from a point A to the point B. From B, she moves 30 km towards west along the same road. If the distance towards east is represented by a positive integer then, how will you represent the distance travelled towards west? By which integer will you represent her final position from A?​

Answer 1

Solution ➼

Since the distance towards east is represented by a positive integer, the distance travelled towards west will be represented by a negative integer.

Distance travelled in east direction =20 km

Distance travelled in west direction =-30 km

Distance travelled from A = 20 + (- 30) = - 10 km

Therefore, we will represent the distance travelled by Rita from point A by a negative integer, i.e., -10 km (i.e., Rita is now in west direction).

Hope it helps you ❤

Answer 2

Step-by-step explanation:

If point A is 0 then

The point B will be +20

If she moves 30 km towards point A and it reached point C (say)

then the distance between point A and point B

= 30-20=10 km

And it in negative side. So it represented as -10
