diameter
runner start at (x,y)=(48 m,0 m)
Runner runs around the circle 2.5 times
i.e. he runs two and half rounds
displacement of two rounds is zero so net displacement is of half round
displacement
After 2.5 round he will be towards west direction with respect to origin
so direction of displacement vector is west
