A political party has to start its procession in an area where wind is blowing at a speed of `30 sqrt(2) km h^-1` and party flags on the cars are fluttering along north - east direction. If the procession starts with a speed of `40 km h^-1` towards north, find the direction of flags on the cars.

Explanation

To solve the problem, we need to determine the direction of the flags on the cars based on the wind velocity and the speed of the procession.

### Step-by-Step Solution:

1. **Identify the Wind Velocity**:
The wind is blowing at a speed of \(30 \sqrt{2} \, \text{km/h}\) in the northeast direction. The northeast direction means it makes a \(45^\circ\) angle with both the north and east axes.

2. **Break Down the Wind Velocity into Components**:
