In a reference frame a man A is moving with velocity `(3hati-4hatj)ms^(-1)` and another man B is moving with velocity `(hati+hatj)ms^(-1)` relative to A. Find the actual velocity of B.

Explanation

To find the actual velocity of man B, we can follow these steps:

### Step 1: Understand the given information
We have:
- Velocity of man A, \( \vec{V_A} = 3 \hat{i} - 4 \hat{j} \) m/s
- Velocity of man B relative to A, \( \vec{V_{B/A}} = \hat{i} + \hat{j} \) m/s

### Step 2: Use the relative velocity formula
