Question

6. 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

Answer:

First, 20 km to East

         20 km

A -----------------------B

Then, 30 km to the west

C-------------A-------------------------------B

                 |---------------20km----------|

|-----------------------30 km----------------|

So we find that the new position, i.e., C is 10km from her starting point to the left (west).

So her final position is 10km to the west.

And since the question says to consider distance towards east as positive, it means that for the distance to the left, it'll be consider as negative.

So you represent her final distance here as -10km, which is a negative integer.
