Question

Задание 4. Реши задачу. [4] Автомобиль ехал до городаб часа со скоростью 100 км/ч, потом до поселка ещё 2 часа со скоростью 40 км/ч. Сколько всего километров проехал автомобиль?​

Answer 1

Ответ:

180 км

Пошаговое объяснение:

100км+(40км*2)=180км

Answer 2

Problem Analysis

To solve this problem, we need to calculate the total distance traveled by the car. The car traveled at a speed of 100 km/h for 1 hour and then at a speed of 40 km/h for 2 hours. We can calculate the total distance by adding the distance traveled at each speed.

Calculation

To calculate the distance traveled at each speed, we can use the formula:

Distance = Speed × Time

For the first part of the journey, the car traveled at a speed of 100 km/h for 1 hour. Therefore, the distance traveled in this part is:

Distance1 = 100 km/h × 1 hour

For the second part of the journey, the car traveled at a speed of 40 km/h for 2 hours. Therefore, the distance traveled in this part is:

Distance2 = 40 km/h × 2 hours

To find the total distance traveled, we can add the distances from both parts:

Total Distance = Distance1 + Distance2

Let's calculate the total distance.

Calculation

Using the given values, we can calculate the total distance traveled by the car.

Distance1 = 100 km/h × 1 hour = 100 km

Distance2 = 40 km/h × 2 hours = 80 km

Total Distance = Distance1 + Distance2 = 100 km + 80 km = 180 km

Therefore, the car traveled a total distance of 180 km.

Answer

The car traveled a total distance of 180 km.
