A person standing at the origin quickly walks 20 m to the right in 30 s. They then slowly walk to the left 10 m in 10 s. The person's path and the magnitude of their displacement are:

Answer 1

The displacement vector is the difference in position vectors from start to finish.

So the magnitude will be 10m, and the direction will be right of the origin,

Distance walked = 20 + 10 = 30 m
