A man walks 10 km South, then 6 km East, then 10 km North 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=6, net y=0
• Distance = sqrt(x^2+y^2) = 6 km
• Direction = East
