What is the average speed of the car if it travels a distance of d km in t h ?

Answer

To find the average speed of a car that travels a distance of \( d \) km in \( t \) hours, we can use the formula for average speed:

### Step-by-Step Solution:

1. **Understand the Formula for Average Speed**:
The average speed is calculated using the formula:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]

2. **Identify the Total Distance and Total Time**:
In this case, the total distance covered by the car is \( d \) km, and the total time taken is \( t \) hours.

3. **Substitute the Values into the Formula**:
Now, we can substitute the values of distance and time into the average speed formula:
\[ \text{Average Speed} = \frac{d \text{ km}}{t \text{ h}} \]

4. **Simplify the Expression**:
The average speed can be expressed as:
\[ \text{Average Speed} = \frac{d}{t} \text{ km/h} \]

### Final Answer:
Thus, the average speed of the car is:
\[ \text{Average Speed} = \frac{d}{t} \text{ km/h} \]
