Question

Из двух городов навстречу друг другу вышли одновременно два поезда один из них проходил в час 35 км в час а другой 42 км через 12 часов поезда встретились найди расстояние между этими городами?

Answer 1

35+42=77 км/час скорость сближения поездов                                                  77*12=924 км расстояние между городами

Answer 2

35•12+42•12=924км-расстояние между городами

Answer 3

Problem Analysis

We have two trains that start from two different cities and travel towards each other. The speed of one train is 35 km/h, and the speed of the other train is 42 km/h. After 12 hours, the trains meet each other. We need to find the distance between these two cities.

Solution

To find the distance between the two cities, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each train and then add them together to find the total distance between the two cities.

Train 1: - Speed: 35 km/h - Time: 12 hours - Distance = 35 km/h x 12 hours = 420 km

Train 2: - Speed: 42 km/h - Time: 12 hours - Distance = 42 km/h x 12 hours = 504 km

Total distance between the two cities = Distance traveled by Train 1 + Distance traveled by Train 2 = 420 km + 504 km = 924 km

Therefore, the distance between the two cities is 924 kilometers.

Conclusion

The distance between the two cities is 924 kilometers.
