Answer 1

Explanation:

...Answer....

Given:−

Velocity of train "A" moving east is 20 m/s.

Velocity of train "B" moving west is 30 m/s.

Explanation:−

As they are moving in east and west direction which is directly opposite to each other.

v ba=v b−va

As compared to velocity of train A is negative as it moves in opposite direction.

v ba=v b−(−va)

v ba=30+20

v ba=50m/s

So, the relative velocity is 50 m/s.
