Question

Со станции одновременно в противоположных направлениях вышли два поезда Скорость одного из них 76 км в час, скорость другого 80 км ч Через сколько часов поезда будут находиться на расстоянии 936 см друг от друга

Answer 1

1) 76 + 80 = 156 (км/ч) - скорость удаления
2) 936 : 156 = 6 (ч)

Ответ: через 6 часов расстояние будет 936 км.

Answer 2

Problem Analysis

We are given that two trains start simultaneously from a station in opposite directions. The speed of one train is 76 km/h, and the speed of the other train is 80 km/h. We need to determine how many hours it will take for the trains to be 936 km apart.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's assume that the time it takes for the trains to be 936 km apart is 't' hours.

The distance covered by the first train in 't' hours is given by:

Distance covered by the first train = Speed of the first train × t

Similarly, the distance covered by the second train in 't' hours is given by:

Distance covered by the second train = Speed of the second train × t

Since the trains are moving in opposite directions, the total distance covered by both trains is the sum of their individual distances:

Total distance covered = Distance covered by the first train + Distance covered by the second train

We can now set up the equation:

936 km = (76 km/h) × t + (80 km/h) × t

Simplifying the equation:

936 km = 156t

Solving for 't':

t = 936 km / 156

Evaluating the expression:

t = 6 hours

Therefore, it will take 6 hours for the trains to be 936 km apart.

Answer

The trains will be 936 km apart from each other after 6 hours.
