Answer 2

Answer:

The velocity of bus A relative to B, $V_{AB}$, calculated is $20kmph$.

Therefore, option 1) $20kmph$ is correct.

Explanation:

Data given,

The speed of bus A, $V_{A}$ = $50kmph$

The speed of bus B, $V_{B}$ = $30kmph$

Here, kmph is kilometre per hour.

Both the buses are travelling in a straight line in the same direction.

The velocity of bus A relative to B, $V_{AB}$ =?

As we know,

• The velocity of bus A relative to B = speed of A - speed of B

Therefore,

• The velocity of bus A relative to B, $V_{AB}$ = $V_{A} - V_{B}$
• The velocity of bus A relative to B, $V_{AB}$ = $(50 -30 )kmph$
• The velocity of bus A relative to B, $V_{AB}$ = $20kmph$.
