Answer 3

Calculating the Average Speed of the Car

To find the average speed of the car for the entire journey, we can use the formula:

Average Speed = Total Distance / Total Time

The car traveled for 3 hours at a speed of 62.6 km/h and then for 2 hours at a speed of 65 km/h.

Calculating the Total Distance

First, we need to calculate the total distance traveled by the car. We can do this by adding the distances traveled during the two segments of the journey.

The distance traveled in the first 3 hours: ``` Distance = Speed * Time Distance = 62.6 km/h * 3 h Distance = 187.8 km ```

The distance traveled in the next 2 hours: ``` Distance = Speed * Time Distance = 65 km/h * 2 h Distance = 130 km ```

Total distance traveled: ``` Total Distance = 187.8 km + 130 km Total Distance = 317.8 km ```

Calculating the Total Time

Next, we need to calculate the total time taken for the entire journey.

Total Time = 3 hours + 2 hours Total Time = 5 hours

Calculating the Average Speed

Now, we can use the formula to calculate the average speed:

Average Speed = Total Distance / Total Time Average Speed = 317.8 km / 5 h Average Speed = 63.56 km/h

The average speed of the car for the entire journey is 63.56 km/h.
