Question

Расстояние между двумя городами 900 км.Навстречу друг другу из этих городов выехали одновременно два автомобиля.Какое расстояние будет между автомобилями через 2 часа если их скорость 110 км.ч и 125 км.ч

Answer 1

1) 110*2 = 220 (км) - проедет 1й автомобиль за 2 часа
2) 125*2 = 250 (км) - проедет 2й автомобиль за 2 часа
3) 220 + 250 = 470 (км) - проедут всего
4) 900 - 470 = 430 (км) расстояник между ними
900 - (110*2 + 125*2) = 430 (км)
Ответ: Расстояние между автомобилями через 2 часа будет 430 км

Я описал длинным способом, если надо кратко - скажи.

Answer 2

S=900-2(110+125)=900-2*235=900-470=430
Ответ 430 км

Answer 3

Problem Analysis

We have two cars traveling towards each other from two different cities. The distance between the cities is 900 km. The cars start at the same time, and we need to find the distance between them after 2 hours, given their speeds of 110 km/h and 125 km/h.

Solution

To find the distance between the two cars after 2 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each car after 2 hours and then find the total distance between them.

Car 1: - Speed: 110 km/h - Time: 2 hours - Distance traveled by Car 1 = 110 km/h × 2 hours = 220 km

Car 2: - Speed: 125 km/h - Time: 2 hours - Distance traveled by Car 2 = 125 km/h × 2 hours = 250 km

Total distance between the cars after 2 hours = Distance traveled by Car 1 + Distance traveled by Car 2 = 220 km + 250 km = 470 km

Therefore, the distance between the two cars after 2 hours will be 470 km.

Answer

The distance between the two cars after 2 hours will be 470 km.
