Calculation of the Car's Speed on Each Segment of the Journey

To find the speed of the car on each segment of the journey, we need to use the formula:

Speed = Distance / Time

Let's calculate the speed on each segment of the journey:

1. Speed on the highway: - Distance: The first segment of the journey on the highway is not specified, so we'll assume it is the remaining distance after the second segment. - Time: The car spent 3 hours on the first segment. - Using the formula, we can calculate the speed on the highway: Speed = Distance / Time. - Since the total distance of the journey is 465 km and the car spent 5 hours on the second segment, the remaining distance after the second segment is 465 km - 5 hours = 460 km. - Therefore, the speed on the highway is: Speed = 460 km / 3 hours.

2. Speed on the dirt road: - Distance: The second segment of the journey on the dirt road is not specified, so we'll assume it is the remaining distance after the first segment. - Time: The car spent 5 hours on the second segment. - Using the formula, we can calculate the speed on the dirt road: Speed = Distance / Time. - Since the total distance of the journey is 465 km and the car spent 3 hours on the first segment, the remaining distance after the first segment is 465 km - 3 hours = 462 km. - Therefore, the speed on the dirt road is: Speed = 462 km / 5 hours.

Now let's calculate the speeds on each segment using the given information and the formulas above.
