Homework Statement
A motorist drives south at 20.0 m/2 for 3.00 min, then turns west and travels at 25.0 m/s for 2 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00 min trip, find (a) the total vector displacement, (b) the average speed, and (c) the average velocity.
Homework Equations
The Attempt at a Solution
Well I tried to convert all that to distance, so multiplying velocity and time. What I don't understand is the north east part. If I were to represent the first part. it would be 3600 m to the south, so -3600j and the second one would be -3000i to and what about the north east part?
