Question

Из двух городов одновременно навстречу друг другу вышли два поезда. Скорость первого поезда 65 км/ч,скорость второго -70 км/ч,он прошел до встречи 350 км.Какой путь до встречи прошел первый поезд? Спасибо!!!

Answer 1

350:70=5 часов до встречи
65*5=325км прошел до встречи первый
350+325=675км все расстояние

Answer 2

Ну тут 2 поезда идут одно и то же время, значит оно равно:
350:70=5 ч.
ищем путь первого:
5*65=325 км.

ответ: 325

Answer 3

Calculating the Distance Traveled by the First Train

To calculate the distance traveled by the first train, we can use the formula:

Distance = Speed × Time

Given: - Speed of the first train = 65 km/h - Speed of the second train = 70 km/h - Total distance traveled by both trains = 350 km

Let's denote the time taken by the first train to meet the second train as "t" hours.

The total distance traveled by both trains is the sum of the distances traveled by each train: Distance of first train + Distance of second train = 350 km

Using the formula, we can calculate the distance traveled by the first train.

Calculation

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

Given: - Speed of the first train = 65 km/h - Speed of the second train = 70 km/h - Total distance traveled by both trains = 350 km

Let's denote the time taken by the first train to meet the second train as "t" hours.

The total distance traveled by both trains is the sum of the distances traveled by each train: Distance of first train + Distance of second train = 350 km

Using the formula, we can calculate the distance traveled by the first train.

The time taken by the first train to meet the second train can be calculated using the formula: Time = Distance / Speed

For the first train: Time = Distance / Speed = 350 / (65 + 70) = 350 / 135 = 2.59 hours

Now, we can calculate the distance traveled by the first train: Distance = Speed × Time = 65 × 2.59 = 168.35 km

So, the first train traveled approximately 168.35 km before meeting the second train.

Conclusion

The first train traveled approximately 168.35 km before meeting the second train.
