A cyclist goes 30 km North and then turning East he goes 40 km. Again he turns right and goes 20 km. After this he turns to his right and goes 40 km. How far is he from his starting point?

Solution

Path:
• 30 km North
• 40 km East
• 20 km South → net North = 30 − 20 = 10
• 40 km West → cancels all East
Net displacement = 10 km North
