You walk 1160 m east and then 1000 m south in a total time of 20 min.
compute your displacement. Enter the east and south components of the displacement separated by a comma.
then
Compute your average velocity in m/s.
Enter the east and south components of the velocity separated by a comma.

(1160 , 1000)

east velocity = 1160/(20*60) = .967 m/s
south velocity = 1000/(20*60) = .833 m/s

total average speed = sqrt (.967^2 +.833^2)
= 1.28 m/s

( .967 , .833 )
