Answer :
-20 mph is the the relative velocity of vba
Va=30 mph
Vb=10 mph
Vab= Vb - Va = 20 mph
Vba=Va - Vb= -20 mph
An object's relative velocity is the speed at which it moves in relation to another object. It serves as a method of determining how swiftly two objects are traveling with respect to one another. Relative velocity is essential to comprehending physics because it helps us grasp how objects move and interact with one another. Relative velocity can be estimated for a variety of interactions.
