Solution Steps

Step 1: Understand the Problem

We need to determine the speed of a person relative to the road outside while they are walking inside a moving bus. The bus is moving at \(100 \, \text{km/h}\) and the person is walking from the back to the front at \(10 \, \text{km/h}\).

Step 2: Relative Speed Calculation

To find the person's speed relative to the road, we need to add the speed of the bus and the speed of the person walking inside the bus. This is because the person is moving in the same direction as the bus.

Step 3: Perform the Addition

The speed of the bus is \(100 \, \text{km/h}\) and the speed of the person walking is \(10 \, \text{km/h}\). Therefore, the total speed relative to the road is: \[ 100 \, \text{km/h} + 10 \, \text{km/h} = 110 \, \text{km/h} \]

Final Answer

\[ \boxed{110 \, \text{km/h}} \]
