Hari traveled 36 kilometers to the west from point P and then 48 kilometers to the east from that point. How far from point P was Hari finally?
Given :
Hari traveled 36 km to the west from point P and then 48 km to the east from that point.
To do :
We have to find how far from point P was Hari finally.
Solution :
If the original position of the Hari (point P) is considered as 0, east of the original position as positive and west of the original position as negative, then
The final position of Hari is, $0+(-36) km + (48 km)=48 km-36 km=+12 km$.
Hari is 12 km to the east of point P.
