Answer 1

56-это7/8  узнаем целое
56:7/8=64 км-второй час

Answer 2

Calculation of the Total Distance Traveled by the Car

To find the total distance traveled by the car in three hours, we need to analyze the information provided in the question.

According to the question, the car traveled 56 km in the first hour, which is 7/8 of the distance it traveled in the second hour. In the third hour, the car traveled 0.75 of the distance it traveled in the second hour.

Let's calculate the distance traveled in the second hour:

Distance traveled in the second hour = (56 km) / (7/8) = 64 km

Now, let's calculate the distance traveled in the third hour:

Distance traveled in the third hour = (64 km) * (0.75) = 48 km

To find the total distance traveled in three hours, we add up the distances traveled in each hour:

Total distance traveled = 56 km + 64 km + 48 km = 168 km

Therefore, the car traveled a total of 168 kilometers in three hours.
