Question

Трактор проехал путь 600 м за время , равное 5 мин , а за следующие 30 мин он проехал путь3,6 км. Какова средняя скорость трактора за всё время движения?

Answer 1

1) 600/5=120м/м - это средняя скорость за 5 мин
2) 1км=1000 м, тогда 3,6км=3600м, тогда 3600/30=120метров в мин.
Ответ: 120 метров в минуту средняя скорость трактора.
Наверное так!

Answer 2

Calculation of Average Speed

To calculate the average speed of the tractor, we need to determine the total distance traveled and the total time taken.

The tractor traveled a distance of 600 meters in 5 minutes and an additional distance of 3.6 kilometers (or 3600 meters) in the next 30 minutes.

To find the total distance traveled, we add the two distances together: 600 meters + 3600 meters = 4200 meters.

To find the total time taken, we add the two time intervals together: 5 minutes + 30 minutes = 35 minutes.

Now, we can calculate the average speed using the formula:

Average Speed = Total Distance / Total Time

Substituting the values, we get:

Average Speed = 4200 meters / 35 minutes

To convert the time from minutes to hours, we divide by 60:

Average Speed = 4200 meters / (35 minutes / 60 minutes per hour)

Simplifying the expression:

Average Speed = 4200 meters / (35/60) hours

Average Speed = 4200 meters / (7/12) hours

To divide by a fraction, we multiply by its reciprocal:

Average Speed = 4200 meters * (12/7) hours

Calculating the result:

Average Speed = 7200 meters per hour

Therefore, the average speed of the tractor for the entire duration of the journey is 7200 meters per hour.
