- If I walk 20 km North, then 15 km East, then 10 km at 35° South of East

1-What is the magnitude of my displacement?

2-What is the angle of my displacement from east?

3-If I travel the entire distance in 4 hours, then what is my average velocity?

I know what x and y components are but this is really confusing me. And the angle I think is the inverse of tan something. part 3 is so confusing smh
