Question

Из двух городов одновременно навстречу друг другу вышли два поезда. Один-со скоростью 48 км/час,а другой 54 км/час. Какое расстояние было между поездами через 12 часов,если расстояние между городами 1822 км. 1) На сколько км приближались поезда за один час 2)какое расстояние преодолеют поезда за 12 часов 3)какое расстояние будет между поездами через 12 часов

Answer 1

1)48+54=102(совокупность скоростей или  скорость  сближения)
2)102х12=1224(км)они преодолеют за 12 часов
3)1822-1224=598(км)расстояние между ними через 12 часов.
4)1224:12=102(км)приближались поезда за 1 час

Answer 2

1)48+54=102(км/ч)- скорость сближения 
2)102•12=1224
3) 1822-1224=598 на вопросы сама ответишь 
я думаю что правельно

Answer 3

Given Information:

- Two trains are traveling towards each other from two different cities. - The first train is traveling at a speed of 48 km/h. - The second train is traveling at a speed of 54 km/h. - The distance between the two cities is 1822 km. - We need to find the following: 1. The rate at which the trains are approaching each other in km/h after one hour. 2. The total distance covered by the trains in 12 hours. 3. The distance between the two trains after 12 hours.

Calculating the Rate of Approach:

To find the rate at which the trains are approaching each other, we can add the speeds of the two trains. The combined speed will give us the rate at which the distance between the trains is decreasing.

The first train is traveling at a speed of 48 km/h, and the second train is traveling at a speed of 54 km/h. Adding these speeds gives us a combined speed of 102 km/h.

Calculating the Total Distance Covered:

To find the total distance covered by the trains in 12 hours, we can multiply the combined speed by the time traveled.

The combined speed of the trains is 102 km/h, and the time traveled is 12 hours. Multiplying these values gives us a total distance covered of 1224 km.

Calculating the Distance Between the Trains:

To find the distance between the two trains after 12 hours, we can subtract the total distance covered by the trains from the initial distance between the cities.

The initial distance between the cities is 1822 km, and the total distance covered by the trains is 1224 km. Subtracting these values gives us a distance between the trains of 598 km.

Summary:

1. The rate at which the trains are approaching each other after one hour is 102 km/h. 2. The total distance covered by the trains in 12 hours is 1224 km. 3. The distance between the two trains after 12 hours is 598 km.
