In a total time of 2.0 min, a duck on a pond paddles 22 m [36 degrees N of E] and then paddles another 65 m [E 25 degrees S]

Determine the duck's

i) total distance travelled

ii) average speed

iii) total displacement

iv) average velocity

2. Relevant equations

ii) v= delta d/t

iii) C = sqrt Cx^2 + Cy^2

iv) still working on it...was focusing on iii) for quite a while

3. The attempt at a solution

i) d = 87 m

ii) v = .73 m/s

iii)Ax = 22 cos 36 = 17.8 Bx = 65 cos 25 = 58.9

Ay = 22 sin 36 = 12.9 By = 65 sin 25 =27.5

Cx = 17.8 + 58.9 = 76.7

Cy = 12.9 + 27.5 = 40.4

C = √(〖Cx〗^2+〖Cy〗^2 )

C = √(5882.89+1632.16)

C = 86.7

Therefore, the total displacement is 86.7 m

I'm hoping I'm at least on the right track...I'm starting an online physics course with absolutely no background. Thanks for any help!
