A car travels a distance of 258 km in 3 hours 35 minutes . What is the speed of the car ?

Answer

To find the speed of the car, we can follow these steps:

### Step 1: Convert the time from hours and minutes to hours only.
The car travels for 3 hours and 35 minutes. We need to convert 35 minutes into hours.

- **Calculation**:
\[ 35 \text{ minutes} = \frac{35}{60} \text{ hours} = \frac{7}{12} \text{ hours} \approx 0.583 \text{ hours} \]

- **Total time in hours**:
\[ 3 \text{ hours} + 0.583 \text{ hours} = 3.583 \text{ hours} \]

### Step 2: Use the formula for speed.
The formula for speed is given by:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

### Step 3: Substitute the values into the formula.
The distance traveled by the car is 258 km, and the time is 3.583 hours.

- **Calculation**:
\[ \text{Speed} = \frac{258 \text{ km}}{3.583 \text{ hours}} \approx 72 \text{ km/h} \]

### Final Answer:
The speed of the car is approximately **72 km/h**.
