Question

2 скоростных поезда отправились одновременно от станции в противоположных направлениях скорость первого поезда 140 км ч Что на 25 км больше скорости второго Найди расстояние между двумя поездами через 2 часа​

Answer 1

140-25=115км/ча скорость второго поезда

115+140=255км/час скорость удаления

255*2=510км расстояние через два часа

Answer 2

#### Problem Analysis We have two high-speed trains that depart simultaneously from a station in opposite directions. The speed of the first train is 140 km/h, and the speed of the second train is 25 km/h less than the first train. We need to find the distance between the two trains after 2 hours. #### Solution To find the distance between the two trains after 2 hours, we can calculate the distance traveled by each train and then find the difference between them. Let's calculate the distance traveled by each train: - The first train travels at a speed of 140 km/h for 2 hours. Therefore, the distance traveled by the first train is **140 km/h * 2 h = 280 km**. - The second train travels at a speed that is 25 km/h less than the first train. So the speed of the second train is 140 km/h - 25 km/h = 115 km/h. Therefore, the distance traveled by the second train is **115 km/h * 2 h = 230 km**. Now, let's find the distance between the two trains by subtracting the distance traveled by the second train from the distance traveled by the first train: - Distance between the two trains = Distance traveled by the first train - Distance traveled by the second train - Distance between the two trains = 280 km - 230 km = 50 km. Therefore, the distance between the two trains after 2 hours is **50 km**. #### Answer The distance between the two high-speed trains after 2 hours is **50 km**.
