Question
I need help with this question. I tried to figure it out but I think I may be wrong.
3240/720=4.5 6. A person drives her car in a straight line at a rate of 25 km/hr for 1hr, then at 50 km/hr for 4hr. She then turns around and drives back the way she came at 20 km/hr for 3hr. a) Find the total distance covered in km. Find the displacement of the car in km. 285 Km = total distance 25+ 200 60=285 I 165 Km = disp1acement %3D b) What was the average speed for the trip? What was the average velocity? 285 = 35.6 Km = Avg. specd 8. 35.6 4.5 Km = Avg velocity-
