Buses A and B are moving in the same direction with speed `20 ms^(-1)` and `15 ms^(-1)` respectively. Find the relative velcoity of A w.r.t. B and relative velocity of B w.r.t. A.

Explanation

To solve the problem of finding the relative velocities of buses A and B, we can follow these steps:

### Step 1: Define the velocities of A and B
Let the velocity of bus A be \( V_A = 20 \, \text{m/s} \) and the velocity of bus B be \( V_B = 15 \, \text{m/s} \). Both buses are moving in the same direction.

### Step 2: Calculate the relative velocity of A with respect to B
The relative velocity of A with respect to B is given by the formula:
\[
