Answer 1

33км в час средняя скорость автомобиля

Answer 2

Calculating the Average Speed of the Car

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

Average Speed = Total Distance / Total Time

First, let's calculate the total distance traveled by the car.

The car first traveled 2 km in 10 minutes and then the remaining distance at a different speed.

The total distance traveled by the car can be calculated as follows:

Total Distance = Distance for the first 2 km + Distance for the remaining part

The time taken to travel the first 2 km is 10 minutes, and the time taken to travel the remaining distance is 5 minutes.

Let's calculate the total distance and then use it to find the average speed of the car for the entire journey.

Calculating the Total Distance

The total distance traveled by the car can be calculated as follows:

Total Distance = Distance for the first 2 km + Distance for the remaining part

The time taken to travel the first 2 km is 10 minutes, and the time taken to travel the remaining distance is 5 minutes.

The distance for the first 2 km can be calculated using the formula: Distance = Speed × Time

The distance for the remaining part can also be calculated using the same formula.

Let's calculate the total distance.

For the first 2 km: Distance = Speed × Time = 2 km

For the remaining part: Distance = Speed × Time = ? km

Calculating the Average Speed

Now that we have the total distance, we can calculate the average speed of the car for the entire journey using the formula:

Average Speed = Total Distance / Total Time

Let's calculate the average speed of the car for the entire journey.
