Question

5.За 6 год поїзд проїхав 432 км. Скільки кілометрів проїде поїзд за 9 год, якщо рухатиметься з тією самою швидкістю? даю 20 балів пжжж​

Answer 1

Ответ:

Пошаговое объяснение:

1) 432 : 6 = 72 (км) - проезжает за 1 час

2) 72 * 9 = 648 (км) - приедет за 9 часов

Ответ: 648 км

Answer 2

To find out how many kilometers the train will travel in 9 hours at the same speed it traveled for 6 years, we need to calculate the average speed of the train and then multiply it by the time of 9 hours.

Calculation:

To calculate the average speed of the train, we divide the total distance traveled by the time taken. In this case, the train traveled 432 kilometers in 6 years, which is equivalent to 6 * 365 = 2190 days, and each day has 24 hours. So the total time taken is 2190 * 24 = 52,560 hours.

The average speed of the train is calculated by dividing the total distance traveled by the total time taken: Average speed = Total distance / Total time

Substituting the values, we have: Average speed = 432 km / 52,560 hours

Now, we can calculate the distance the train will travel in 9 hours by multiplying the average speed by the time of 9 hours: Distance = Average speed * Time

Substituting the values, we have: Distance = (432 km / 52,560 hours) * 9 hours

Let's calculate the result:

Calculation:

Distance = (432 km / 52,560 hours) * 9 hours

Using a calculator, we find that the train will travel approximately 0.0732 kilometers in 9 hours at the same speed it traveled for 6 years.

Please note that the answer is rounded to four decimal places for simplicity.
