Answer 2

We need to know how far Pawan drove his car

• Pawan drove his car on a rectangular route
• Pavan started at point A
• After driving to point A he drove $80$ km left to point B
• After reaching point B he drove $100$ km left to point C
• After reaching point C he drove $80$ km left again to point D
• After reaching point D he drove $120$ km back towards point A
• He then drove beyond point A for anti $20$ km
• So Pawan drove $20$ km  from his starting point
