You are taking a short trip at constant speed (entire trip) in your car from point A to point B and then finally from point B to point C. The distance from point A to point B is 80 miles in a northeasterly direction (45 degrees north of east). Next, you head directly east for 130 miles from point B to point C. The entire trip takes you 3 hours.

a) Draw a rough graph of the total change in position, or displacement. Might this be a vector arrangement? 

b) What is the average speed for the trip?

c) Solve for the resultant vector from point A to point C?

d) Is the average velocity for the trip the same as the average speed? Yes, or No. If not, please calculate the average velocity for the trip.

e) List some ways that things might change if the speed from point A to point B is 1.5 times the speed from point B to point C?
