Question

Поезд был в пути 3 часа и прошел 230 км за первый час он проехал 78 км 500 м за второй час на 6 км меньше чем за первый какой путь прошел поезд за 3 часа

Answer 1

За второй час поезд проехал 78 км 500 м - 6 км = 72 км 500 м
За третий час поезд проехал 230 км - ( 72 км 500 м + 78 км 500 м ) = 230 км - 151 км = 79 км
Ответ: За второй час 72 км 500 м ; за третий час 79 км.

Answer 2

Calculation of the Train's Total Distance Traveled

To calculate the total distance traveled by the train in 3 hours, we need to add up the distances covered in each hour.

- In the first hour, the train traveled 230 km. - In the second hour, the train traveled 78 km 500 m, which is 6 km less than the distance covered in the first hour. - In the third hour, we don't have the exact distance traveled.

To find the distance traveled in the third hour, we can subtract the sum of the distances covered in the first two hours from the total distance traveled in 3 hours.

Let's calculate it step by step:

1. Distance covered in the first hour: 230 km. 2. Distance covered in the second hour: 78 km 500 m, which is 6 km less than the distance covered in the first hour. So, the distance covered in the second hour is 230 km - 6 km = 224 km. 3. Total distance covered in the first two hours: 230 km + 224 km = 454 km.

Now, let's find the distance covered in the third hour:

- Total distance traveled in 3 hours: 454 km + Distance covered in the third hour.

To find the distance covered in the third hour, we subtract the sum of the distances covered in the first two hours from the total distance traveled in 3 hours:

- Distance covered in the third hour = Total distance traveled in 3 hours - Total distance covered in the first two hours.

Let's calculate it:

- Distance covered in the third hour = 454 km - (230 km + 224 km) = 454 km - 454 km = 0 km.

Therefore, the train covered 0 km in the third hour.

To find the total distance traveled by the train in 3 hours, we add up the distances covered in each hour:

- Total distance traveled by the train in 3 hours = Distance covered in the first hour + Distance covered in the second hour + Distance covered in the third hour = 230 km + 224 km + 0 km = 454 km.

Therefore, the train traveled a total distance of 454 km in 3 hours.
