Answer 1

Ответ:

6

Пошаговое объяснение:

60+90=150 км/час (скорость сближения)

Answer 2

Problem Analysis

We are given that two trains start from two different cities and are traveling towards each other. The speed of the first train is 60 km/h, and the speed of the second train is 90 km/h. The distance between the cities is 900 km. We need to find out how many hours it will take for the trains to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the trains to meet.

For the first train: - Speed = 60 km/h - Distance = 900 km - Time = Distance / Speed = 900 km / 60 km/h = 15 hours

For the second train: - Speed = 90 km/h - Distance = 900 km - Time = Distance / Speed = 900 km / 90 km/h = 10 hours

Since both trains started at the same time, the time it will take for them to meet is the same for both trains. Therefore, the trains will meet in 10 hours.

Answer

The two trains will meet in 10 hours.
