Question

Два поезда вышли одновременно из двух городов и встретились на промежуточной станции через 4 часа. Скорость одного 85км/ч а другого на 6 км/ч больше .вычесли расстояние между городами

Answer 1

1)85*4=340км проехал до станции один позд; 2) (85+6)*4=364км проехал второй до станции; 3)340+364=704км растояние между городами

Answer 2

Problem Analysis

We have two trains that leave two different cities simultaneously and meet at an intermediate station after 4 hours. The speed of one train is 85 km/h, while the speed of the other train is 6 km/h faster. We need to calculate the distance between the two cities.

Solution

Let's assume the speed of the second train is x km/h. Since the speed of the second train is 6 km/h faster than the first train, its speed can be represented as (85 + 6) km/h = 91 km/h.

We know that distance = speed × time. The time taken by both trains to meet at the intermediate station is 4 hours.

Let's calculate the distance between the two cities using the formula:

Distance = Speed × Time

For the first train: Distance1 = 85 km/h × 4 h = 340 km

For the second train: Distance2 = 91 km/h × 4 h = 364 km

Since the two trains meet at the intermediate station, the sum of the distances covered by both trains will give us the total distance between the two cities.

Total Distance = Distance1 + Distance2

Total Distance = 340 km + 364 km = 704 km

Therefore, the distance between the two cities is 704 km.

Answer

The distance between the two cities is 704 km.
