A man walks 5 km North, then 3 km East, then 5 km South from his starting point. How far and in which direction is he now from the starting point?

Explanation

• Track net displacement: East(+)/West(-) on x-axis, North(+)/South(-) on y-axis
• Net x=3, net y=0
• Distance = sqrt(x^2+y^2) = 3 km
• Direction = East
