The relation between speed and displacement is

Options

A. displacement=speed/time
B. displacement=speed x time
C. displacement=time/speed
D. none of the above

Answer

To solve the question regarding the relation between speed and displacement, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- Speed is defined as the distance traveled per unit of time. It can be mathematically expressed as:
\[ \text{Speed} = \frac{\text{Displacement}}{\text{Time}} \]

2. **Rearranging the Formula**:
- From the formula above, we can rearrange it to express displacement in terms of speed and time. By multiplying both sides by time, we get:
\[ \text{Displacement} = \text{Speed} \times \text{Time} \]

3. **Conclusion**:
- Therefore, the relation between speed and displacement is that displacement is equal to speed multiplied by time. This means that if you know the speed of an object and the time it has been moving, you can calculate the displacement.

4. **Select the Correct Option**:
- Based on the options provided, the correct relation is:
\[ \text{Displacement} = \text{Speed} \times \text{Time} \]
- Thus, the answer is option 2.
