Question

Два поезда идут навстречу друг другу Из двух городов первый поезд прошел до встречи 78 км 2 в 3 раза больше чем 1 Чему равна длина пути между этими городами именно на сколько километров меньше пошел навстречу первый поезд чем

Answer 1

78×3=234км(1)
234+78=312км (длина пути)
234-78=156км (на>)

Answer 2

Calculating the Distance Between Two Cities

To find the distance between two cities and the difference in the distances traveled by two trains, we can use the information provided.

Let's denote: - The distance between the two cities as x kilometers. - The distance traveled by the first train as 78 kilometers. - The distance traveled by the second train as 3 times the distance traveled by the first train.

Calculating the Distance Traveled by the Second Train

The distance traveled by the second train can be calculated as follows: - Let's denote the distance traveled by the second train as 3d (where d is the distance traveled by the first train). - According to the information provided, the distance traveled by the second train is 3 times the distance traveled by the first train.

Therefore, the distance traveled by the second train (3d) is 3 * 78 = 234 kilometers.

Calculating the Distance Between the Two Cities

The total distance between the two cities can be calculated by adding the distances traveled by both trains: - Total distance = Distance traveled by the first train + Distance traveled by the second train - Total distance = 78 + 234 = 312 kilometers

Finding the Difference in Distances Traveled by the Trains

To find the difference in the distances traveled by the two trains, we can subtract the distance traveled by the first train from the distance traveled by the second train: - Difference = Distance traveled by the second train - Distance traveled by the first train - Difference = 234 - 78 = 156 kilometers

Therefore, the length of the path between the two cities is 312 kilometers, and the first train traveled 156 kilometers less than the distance between the two cities.
