A car travelled `235 km` north from Delhi and then `756 km` south of it. How far from Delhi is the car ?

Answer

To solve the problem step by step, we will analyze the movements of the car and use integers to represent the distances traveled in different directions.

### Step-by-Step Solution:

1. **Identify the Directions**:
- The car first travels **north** from Delhi.
- Then, it travels **south**.

2. **Assign Values to the Distances**:
- The distance traveled **north** is **235 km**. We can represent this as a positive integer:
\[ \text{Distance North} = +235 \text{ km} \]
- The distance traveled **south** is **756 km**. Since south is the opposite direction of north, we represent this as a negative integer:
\[ \text{Distance South} = -756 \text{ km} \]

3. **Calculate the Total Distance from Delhi**:
- To find the total distance from Delhi, we add the distances:
\[ \text{Total Distance} = \text{Distance North} + \text{Distance South} \]
\[ \text{Total Distance} = +235 + (-756) \]
\[ \text{Total Distance} = 235 - 756 \]
\[ \text{Total Distance} = -521 \text{ km} \]

4. **Interpret the Result**:
- The negative sign indicates that the car is **521 km south** of Delhi. Therefore, the distance from Delhi is:
\[ \text{Distance from Delhi} = 521 \text{ km} \]

### Final Answer:
The car is **521 km** away from Delhi, in the south direction.
