The distance covered by an object in a unit time is called the _______ of that object.

Options

A. Time
B. Distance
C. Speed
D. All of the above

Answer

To solve the question "The distance covered by an object in a unit time is called the _______ of that object," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for a term that describes the relationship between distance and time for an object in motion.

2. **Identify Key Terms**:
- **Distance**: This refers to how far an object has traveled.
- **Time**: This is the duration over which the distance is measured.
- **Speed**: This is a measure of how quickly an object covers distance over time.

3. **Recall the Definition of Speed**:
- Speed is defined as the distance traveled by an object in a unit of time. Mathematically, it can be expressed as:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
- This means that speed tells us how much distance is covered in a specific time period.

4. **Analyze the Options**: The options provided are:
- A) Time
- B) Distance
- C) Speed
- D) All of the above

5. **Eliminate Incorrect Options**:
- **Time**: This does not describe the distance covered; it is merely a measure of duration.
- **Distance**: This is the measure of how far an object has traveled but does not account for the time taken.
- **All of the above**: This option cannot be correct since only one term accurately describes the relationship.

6. **Select the Correct Answer**: The only term that accurately describes the distance covered in a unit time is **Speed**.

### Final Answer:
The distance covered by an object in a unit time is called the **Speed** of that object.
