Answer:
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
