A car covers a distance of 276.75 km in 4.5 hours. What is the average speed of the car ?

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 = 276.75 km
- Time taken = 4.5 hours

### Step 2: Substitute the values into the formula
Now, we will substitute the values into the speed formula:

\[ \text{Speed} = \frac{276.75 \text{ km}}{4.5 \text{ hours}} \]

### Step 3: Perform the division
To simplify the division, we can eliminate the decimals. We can multiply both the numerator and the denominator by 10 to make the division easier:

\[ \text{Speed} = \frac{2767.5}{45} \]

### Step 4: Simplify the fraction
Next, we can simplify the fraction. We can divide both the numerator and the denominator by 5:

- \( 2767.5 \div 5 = 553.5 \)
- \( 45 \div 5 = 9 \)

So now we have:

\[ \text{Speed} = \frac{553.5}{9} \]

### Step 5: Perform the final division
Now, we will divide 553.5 by 9:

\[ 553.5 \div 9 = 61.5 \]

### Step 6: State the final answer
Thus, the average speed of the car is:

\[ \text{Average Speed} = 61.5 \text{ km/h} \]
