Question

Как решить задачу? Поезд движется со скоростью 120 км/ч за сколько минут поезд преодолеет расстояние 8000м?

Answer 1

1.) 120:60=2(км)-поезд проходит за 1 мин. 2 км 2000м .
2.) 8000:2000=4(мин.)
Ответ: за 4 минуты поезд преодолеет расстояние.

Answer 2

Problem:

We need to find out how many minutes it will take for a train traveling at a speed of 120 km/h to cover a distance of 8000 meters.

Solution:

To solve this problem, we can use the formula:

time = distance / speed

Let's plug in the given values:

distance = 8000 meters speed = 120 km/h

To use the formula, we need to make sure that the units are consistent. Since the speed is given in kilometers per hour and the distance is given in meters, we need to convert the speed to meters per minute.

To convert kilometers per hour to meters per minute, we can use the conversion factor:

1 kilometer = 1000 meters 1 hour = 60 minutes

Therefore, the conversion factor is:

1 kilometer per hour = (1000 meters) / (60 minutes)

Now, let's calculate the time it will take for the train to cover the given distance:

time = (distance / speed) * (1 kilometer per hour / (1000 meters / 60 minutes))

Simplifying the equation:

time = (8000 meters / 120 km/h) * (1 kilometer per hour / (1000 meters / 60 minutes))

Calculating the result:

time = (8000 / 120) * (60 / 1000) minutes

time = 400 * 0.06 minutes

time = 24 minutes

Therefore, it will take the train 24 minutes to cover a distance of 8000 meters at a speed of 120 km/h.
