Question

6. Автомобиль ехал 30 мин. со скоростью 40 км/ч, затем 2 часа стоял, а потом ехал еще 2 ч со скоростью 90 км/ч. Найдите пройденный путь автомобиля [2]

Answer 1

30 мин = 0,5 часа. Путь на первом участке равен 0,5*40 = 20км. Путь на втором участке равен 2*90 = 180км. 180+20 = 200км

Ответ: 200км

Answer 2

Calculation of the Distance Traveled by the Car

To calculate the distance traveled by the car, we need to consider the different segments of the journey and calculate the distance for each segment separately.

1. Segment 1: The car traveled for 30 minutes at a speed of 40 km/h. - Time: 30 minutes = 0.5 hours - Speed: 40 km/h - Distance = Speed x Time = 40 km/h x 0.5 hours = 20 km

2. Segment 2: The car was stationary for 2 hours and did not cover any distance.

3. Segment 3: The car traveled for 2 hours at a speed of 90 km/h. - Time: 2 hours - Speed: 90 km/h - Distance = Speed x Time = 90 km/h x 2 hours = 180 km

Therefore, the total distance traveled by the car is 20 km + 0 km + 180 km = 200 km. Please note that the specific make and model of the car were not provided, so the calculation is based on general principles of distance, time, and speed.
