Question

из двух пунктов,расстояние между которыми 210 км,вышли одновременно навстречу друг другу два электропоезда. скорость одного из них на 5 км/ч больше скорости другого. найдите скорость каждогол электропоезда,если они встретились через 2 часа после своего выхода.

Answer 1

У первого скорость 105 км/ч , а у второго 110 км/ч

Answer 2

Calculating the Speed of Each Train

To find the speed of each train, we can use the formula:

Speed = Distance / Time

Given: - Distance between the trains = 210 km - Time taken to meet = 2 hours

Let's denote: - Speed of the slower train as S km/h - Speed of the faster train as S + 5 km/h

Using the formula, we can set up the following equation based on the given information:

For the slower train: 210 = 2S

For the faster train: 210 = 2(S + 5)

Let's solve these equations to find the speeds of the trains.

Calculations

Using the first equation, we can solve for the speed of the slower train: S = 210 / 2 = 105 km/h

Then, using the second equation, we can find the speed of the faster train: S + 5 = 105 + 5 = 110 km/h

Conclusion

Therefore, the speed of the slower train is 105 km/h and the speed of the faster train is 110 km/h.
