Question

Два поезда вышли одновременно навстречу друг другу из двух городов, расстояние между которыми 970 км. Скорость первого 75 км/ч, а скорость второго поезда 85 км/ч. Какое расстояние будет между поездами через 5 часов после выхода?

Answer 1

170 Километров так как 75+85=160 160*5=800 970-800=170

Answer 2

Problem Analysis

We have two trains traveling towards each other from two different cities. The distance between the cities is 970 km. The first train has a speed of 75 km/h, and the second train has a speed of 85 km/h. We need to calculate the distance between the trains after 5 hours.

Calculation

To calculate the distance between the trains after 5 hours, we need to determine how far each train has traveled in that time.

The distance traveled by the first train can be calculated using the formula: Distance = Speed × Time

For the first train: Distance = 75 km/h × 5 h = 375 km

Similarly, the distance traveled by the second train can be calculated as: Distance = 85 km/h × 5 h = 425 km

Since the trains are traveling towards each other, the distance between them after 5 hours can be calculated by subtracting the distance traveled by the first train from the total distance between the cities: Distance between trains = Total distance - Distance traveled by first train

Distance between trains = 970 km - 375 km = 595 km

Answer

After 5 hours, the distance between the two trains will be 595 km.
