A car travels 60km in the first hour , 65km in the second hour , 70km in the third hour, then the average speed of the car is

Options

A. 66 km/hr
B. 62 km/hr
C. 56 km/hr
D. 65 km/hr

Answer

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

### Step 1: Calculate the total distance traveled
The car travels different distances in each hour:
- In the first hour, the car travels 60 km.
- In the second hour, the car travels 65 km.
- In the third hour, the car travels 70 km.

Now, we add these distances together to find the total distance traveled:
\[ \text{Total Distance} = 60 \text{ km} + 65 \text{ km} + 70 \text{ km} \]
\[ \text{Total Distance} = 195 \text{ km} \]

### Step 2: Calculate the total time taken
The car travels for a total of 3 hours (1 hour for each segment of the journey):
\[ \text{Total Time} = 1 \text{ hour} + 1 \text{ hour} + 1 \text{ hour} = 3 \text{ hours} \]

### Step 3: Calculate the average speed
Average speed is calculated using the formula:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \]
Substituting the values we calculated:
\[ \text{Average Speed} = \frac{195 \text{ km}}{3 \text{ hours}} = 65 \text{ km/h} \]

### Conclusion
The average speed of the car is **65 km/h**.
