Write the dimensional formula of speed.

Explanation

To find the dimensional formula of speed, we follow these steps:

### Step 1: Understand the definition of speed
Speed is defined as the distance traveled per unit of time. Mathematically, it can be expressed as:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

### Step 2: Identify the dimensions of distance and time
- Distance is measured in units of length (L). In dimensional analysis, we denote length with the symbol \( L \).
