Calculating average velocity or speed (video) Khan Academy

WebFeb 20, 2024 · Thus average speed is not simply the magnitude of average velocity. Figure 1.4.3: During a 30-minute round trip to the store, the total distance traveled is 6 km. The average speed is 12 km/h. The displacement for the round trip is zero, since there was no net change in position. Thus the average velocity is zero. WebWe see that the range equation has the initial speed and angle, so we can solve for the initial speed for both (a) and (b). When we have the initial speed, we can use this value to write the trajectory equation.

Yes, instead of multiplying by time you can just plug the numbers into the equation: time = distance / rate (speed). In this case it would be: time = 720m / 3m per sec. When you divide 720m by 3m/s the meters cancels out and you are then left with time which would be 240 seconds.
