What is the average velocity between 0.6 h and 1 h?
A. + 0.4 km/h
B. + 1.25 km/h
C. + 1.66 km/h
D. + 2.5 km/h
This questions is hard for me to understand because you can only find average velocity by dividing the displacement by the time, and here they don't give you displacement.

What is the object's displacement between 0.4 h and 0.6 h?
A. 0.75 km
B. +0.25 km
C. +0.75 km
D. +1.0 km
This questions is the same as well, can you show me what to do. You can show me an example like this questions if you really want.
