I am just aweful at this vector stuff, i can NEVER get it right.(adsbygoogle = window.adsbygoogle || []).push({});

A motorist drives south at 20.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.20 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.20 min trip, find the following values.

(a) total vector displacement

(b) average speedi got this part already, easy

(c) average velocity (include the magnitude)

total displacement i got 6291 meters (rounded). i did this by figuring out each x and y coordinate for the vectors, then adding them up, and finding the hypotenuse of the resulting vector. apparentlys its not right. As for the velocity part, i was unsure of how to go about starting it...
