Question

За 7 ч. тракторист вспахал 4,9 га.С какой скоростью двигался трактор, если ширина полосы вспахиваемая плугами равна 1,75 га.

Answer 1

4,9 / 7 * 1,75

Я считаю, что так.

Answer 2

Площадь (4,9га) делим на ширину проходки (1,75га) получаем длину. Затем полученную длину делим на затраченное время, получаем скорость. Итак, 4,9 / 1,75 = 2,8; 2,8/7=0,4. Ответ: Скорость движения трактора 0,4м/час.

Answer 3

Calculation of Tractor Speed

To calculate the speed at which the tractor was moving, we need to use the given information.

The tractorist plowed 4.9 hectares (ha) in 7 hours. The width of the plowed strip is 1.75 ha.

To find the speed, we can divide the total area plowed by the time taken:

Speed = Total Area / Time

Let's calculate the speed:

Total Area = 4.9 ha

Time = 7 hours

Speed = 4.9 ha / 7 hours

Using a calculator, we can find that the speed of the tractor was approximately 0.7 hectares per hour.

Please note that the given question does not provide any additional information about the speed or any other factors that could affect the calculation.
