1. The problem statement, all variables and given/known data

A bird flies from Lesser Slave Lake in northern Alberta to Dore Lake in northern Saskatchewan. The birds displacement is 800.0 km [E 7.5deg S]. The bird then flies from Dore Lake to Big Quill Lake, Saskatchewan. This displacement is 400.0 km [E 51deg S]. The total time of the flight is 18.0 hours. Determine the bird's
1. total distance traveled
2. total displacement
3. average speed
4. average velocity

2. Relevant equations
Very many kinematic equations
∇Velx = Vfx - Vix
∇Vely = Vfy - Viy
ΔVel = √Vx^2 + Vy^2

Etc.

In order to provide you with help we need to see your attempt at solving the problem. Do you understand what each of the things you're asked to find is? For example, can you explain what the total distance traveled is? Can you explain what the total displacement is? I recommend you review you notes from class or refer to your textbook (or other online resources) if not. Once you understand these concepts and the difference between them the problem should be much easier.

If you're having difficulty ask for help, but we need to see some kind of attempt first. :)
