Determine the velocity of car A with respect to car B

Explanation:

There are generally two cases, the first when vehicles ( cars) are going in the same direction and the second is when they are going in the opposite direction, ie. to meet each other.

This is defined by the so-called classical law of velocity summation.

First situation:

Cars are going in the same direction and suppose the speed of the car A is greater than the speed of the car B.

Va > Vb

We simplify this situation by assuming that car B stands and car A moves away from them at a speed equal to their difference

V = Va - Vb

Second situation:

Cars are going in the opposite direction, ie. to meet each other.

It doesn't matter whose speed is higher

We simplify this situation by assuming that car B stands and car A is moving toward car B at a speed equal to their sum or car A stands and car B is moving toward car A at a speed equal to their sum

V = Va + Vb

God is with you!!!

where is the circuit diagram ?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
