Ang Velocity is /Delta x divided by /delta t correct?

and avg speed is just adding the distance's and times and diving by the time right?

Well for the avg velocity for this problem its saying its wrong any help?

Show exactly what you did. To find the average velocity, start by finding the displacement.

Did velocity avg by 960-400/1.5-.75 = 747 and it says its wrong....

You found the correct displacement, nowbadtwistoffate said:found displacement by using a right-hand coordinate system. and did solved by doing a^2 + b^2 = c^2. got the displacement to be 1040 km for the total trip. (Checked it its right)

I have no idea what you are calculating here. What happened to the displacement that you just calculated?Did velocity avg by 960-400/1.5-.75 = 747 and it says its wrong....

960 and 400 was the two distances, how to apply the displacement? do i subtract from that?!

Average velocity is just displacement divided by time. Do it!

but what does my schaums outline says change in x over change in timee, im confused :(

is it displacement over change in time or total time?

also isnt displacement delta x?

is it displacement over change in time or total time?

also isnt displacement delta x?
