Question

СРОЧНО ПОМОГИТЕ!! ЛЕГКОв ЗАДАНИЕ! Первые 500 м пути трактора проехал за время равное 4 минутам ,а за следующие 10 минут проехал 2 км. Определите среднюю скорость трактора за все время движения

Answer 1

2000 м+500 м=2500 м - расстояние
4 мин+10 мин=14 мин
2500:14=178 6\7 (м\мин) - средняя скорость трактора
Ответ: 178 6\7 м\мин.

Answer 2

Task Analysis

To solve this problem, we need to find the average speed of the tractor for the entire duration of its movement. We are given that the tractor traveled the first 500 meters in 4 minutes and the next 2 kilometers in 10 minutes.

Solution

To find the average speed, we need to calculate the total distance traveled and the total time taken. Then, we can divide the total distance by the total time to find the average speed.

Let's calculate the total distance traveled: - The tractor traveled the first 500 meters. - The tractor also traveled 2 kilometers, which is equivalent to 2000 meters.

So, the total distance traveled is 500 meters + 2000 meters = 2500 meters.

Next, let's calculate the total time taken: - The tractor took 4 minutes to travel the first 500 meters. - The tractor took 10 minutes to travel the next 2000 meters.

So, the total time taken is 4 minutes + 10 minutes = 14 minutes.

Now, let's convert the total time taken to hours: - There are 60 minutes in an hour, so 14 minutes is equal to 14/60 = 0.2333 hours (rounded to four decimal places).

Finally, we can calculate the average speed by dividing the total distance by the total time: - Average speed = Total distance / Total time - Average speed = 2500 meters / 0.2333 hours

Let's calculate the average speed.
