Question

В первый час автобус прошёл 40% всего пути во второй час 1/3 пути, а втретий остальные 28 киллометров. Какое расстояние автобус прошёл за три часа

Answer 1

Обозначим весь путь за х. Тогнда в первый час автобус прошел 0,4х пути, во второй час 1/3х, осталось 28 км
Составим уравнение:
х - 0,4х - 1/3х = 28 (умножим все уравнение на 3)
3х - 1,2х - х = 84
0,8х = 84

Answer 2

Calculating the Distance Traveled by the Bus

To calculate the distance the bus traveled in three hours, we can break down the information provided:

1. First Hour: The bus traveled 40% of the total distance. 2. Second Hour: The bus traveled 1/3 of the total distance. 3. Third Hour: The bus traveled the remaining 28 kilometers.

Calculations

1. First Hour: If the bus traveled 40% of the total distance in the first hour, we can calculate this as follows: - Let's assume the total distance is represented by D. - The distance traveled in the first hour is 40% of D, which can be expressed as 0.4D.

2. Second Hour: If the bus traveled 1/3 of the total distance in the second hour, we can calculate this as follows: - The distance traveled in the second hour is 1/3 of D, which can be expressed as (1/3)D.

3. Third Hour: The bus traveled the remaining 28 kilometers.

Total Distance Traveled

To find the total distance traveled in three hours, we can sum the distances traveled in each hour:

Total Distance = Distance in First Hour + Distance in Second Hour + Distance in Third Hour

Total Distance = 0.4D + (1/3)D + 28

Now, we can solve for D to find the total distance traveled by the bus in three hours.
