"A jogger runs with a velocity of 6.0 km/h [25° N of W] for 35 min and then changes direction, jogging for 20 min at 4.5 km/h [65° E of N]. Using a vector diagram, determine the jogger's total displacement and his average velocity for the workout."

Question

I know the answer, what I would appreciate is knowing how to get. Because it doesn't happen in the same amount of time I know I cannot use x/y components and I'm unsure of what else to do. Any help would be appreciated, thank you.

Answer 1

work in distances: distance=speed*time

then add the x,y compnents of distances
