प्रश्न
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?
उत्तर
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).
