Since your start and end points for the try are the same point, your displacement for the trip is zero. Since the magnitude of velocity is (displacement) divided by (time), the average velocity is also zero. The correct choice is (E).
You first travel 100km in 1 hour which makes your velocity 100km/h (100/1=100) You then travel 100km in 2 hours which makes your velocity 50km/h (100/2=50) You then travel 100km in 3 hours which makes your velocity 33.3km/h (100/3=33.3) Finally, you travel 100km in 4 hours which makes your velocity 25 km/h (100/4=25)
Add up all your velocities (100+50+33.3+25) which makes 208.3 You then divide it by 4 since you have 4 travels. 208.3 / 4 = 52,075
So I would say the answer is E in this case since none of the answers is close to 52km/hr
The average velocity for the total trip is 0 km/h because the displacement is zero, meaning the start and end points are the same. Therefore, the best choice from the options given is (E) None of the above.
