Question

Трактор проехал путь 600м за время равное 5мин ,а следующие 30мин он проехал путь 3,6 км. Какова средняя скорость трактора за все это время ?

Answer 1

Vср=(S1+S2)/(t1+t2)=600+3600/(60×5+30×60)=2м/с

Answer 2

3,6 км=3600м
5+30=35 минут - всего двигался трактор
(3600+600)/35=120 м/мин - средняя скорость

Answer 3

Calculation of Average Speed

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

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

To calculate the total distance, we need to convert the distance traveled in kilometers to meters. Since 1 kilometer is equal to 1000 meters, the additional distance of 3.6 kilometers is equal to 3.6 * 1000 = 3600 meters.

The total distance traveled by the tractor is 600 meters + 3600 meters = 4200 meters.

The total time taken is 5 minutes + 30 minutes = 35 minutes.

To calculate the average speed, we divide the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 4200 meters / 35 minutes

Now, let's convert the time from minutes to hours. Since there are 60 minutes in an hour, the time in hours is 35 minutes / 60 = 0.5833 hours.

Average Speed = 4200 meters / 0.5833 hours

Using a calculator, we can find the average speed of the tractor.

The average speed of the tractor for the given time is approximately 7197.6 meters per hour.
