An aeroplane is flying with a velocity 800kmph relative to air wind is belong from west to east with a velocity 15`ms^(-1)`. Find velocity of aeroplane relative to the earth to fly south ward

Explanation

To solve the problem of finding the velocity of the airplane relative to the Earth while flying southward, we can break it down into several steps:

### Step 1: Understand the Given Information
- The airplane's velocity relative to the air is \(800 \text{ km/h}\).
- The wind's velocity is \(15 \text{ m/s}\) from west to east.
- We need to find the airplane's velocity relative to the Earth while it is flying southward.

### Step 2: Convert the Airplane's Velocity to the Same Units
