State, which of the following variables are continuous and which are discrete :
distance travelled by a car.

Answer

To determine whether the variable "distance travelled by a car" is continuous or discrete, we can follow these steps:

### Step 1: Define Continuous and Discrete Variables
- **Continuous Variables**: These are variables that can take any value within a given range. They are measured and can be represented as decimals. Examples include height, weight, and distance.
- **Discrete Variables**: These are variables that can only take specific, distinct values. They are counted and are usually whole numbers. Examples include the number of students in a class, number of cars in a parking lot, etc.

### Step 2: Analyze the Variable
- The variable in question is "distance travelled by a car."

### Step 3: Determine the Nature of the Variable
- Distance can be measured in various units (like kilometers or miles) and can take any value, including fractions (e.g., 10.5 km, 15.75 km).

### Step 4: Conclusion
- Since distance can be measured and can take on decimal values, it is classified as a **continuous variable**.

### Final Answer
- The distance travelled by a car is a **continuous variable**.
