A car covers a distance of 690 km in 30 h. What is the average speed of the car?

Options

A. 25 km/h
B. 23 km/h
C. 20 km/h
D. 18 km/h

Answer

To find the average speed of the car, we can use the formula for speed, which is:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

### Step 1: Identify the given values
- Distance covered by the car = 690 km
- Time taken = 30 hours

### Step 2: Substitute the values into the formula
Now, we can substitute the given values into the formula:

\[ \text{Speed} = \frac{690 \text{ km}}{30 \text{ h}} \]

### Step 3: Perform the division
Next, we perform the division to find the speed:

\[ \text{Speed} = \frac{690}{30} \]

Calculating this gives:

\[ \text{Speed} = 23 \text{ km/h} \]

### Step 4: State the final answer
Therefore, the average speed of the car is:

\[ \text{Average Speed} = 23 \text{ km/h} \]
