Question

Два поезда отошли одновременно навстречу друг другу от двух станций между которыми 350 км.первый поезд едет со скоростью 85км/ч,а второй 95 км/ч. какое расстояние будет между этими поездами через 1 час?

Answer 1

1) 95+85=180 2) 350-180=170 Ответ: расстояние между поездами через 1час будет 170 км.

Answer 2

Problem Analysis

We are given two trains that depart simultaneously from two different stations towards each other. The distance between the stations is 350 km. The first train travels at a speed of 85 km/h, and the second train travels at a speed of 95 km/h. We need to find the distance between the two trains after 1 hour.

Solution

To find the distance between the two trains after 1 hour, we need to calculate the distance each train has traveled in that time.

Let's calculate the distance traveled by the first train after 1 hour: - Speed of the first train = 85 km/h - Time traveled by the first train = 1 hour - Distance traveled by the first train = Speed * Time = 85 km/h * 1 hour = 85 km

Now, let's calculate the distance traveled by the second train after 1 hour: - Speed of the second train = 95 km/h - Time traveled by the second train = 1 hour - Distance traveled by the second train = Speed * Time = 95 km/h * 1 hour = 95 km

To find the distance between the two trains after 1 hour, we subtract the distance traveled by the first train from the total distance between the stations: - Total distance between the stations = 350 km - Distance between the two trains after 1 hour = Total distance - Distance traveled by the first train = 350 km - 85 km = 265 km

Therefore, the distance between the two trains after 1 hour is 265 km.
