Detailed Solution
Download Solution PDFVarun's movements:
Net displacement in North direction = 7 km - 9 km + 2 km = 0 km
Net displacement in East direction = -4 km + 8 km = 4 km
So, Point P is 4 km East of Point A.
To reach Point A from Point P, Varun needs to drive 4 km towards the West.
Hence, the correct answer is "Option 1"
