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

4,9га =49000м2
1)49000: 1,75=28000 м
2)28000:7=4000м/ч = 4км/ч

Answer 2

Calculation

To calculate the speed at which the tractor was moving, we can use the given information. The tractorist plowed 4.9 hectares (ha) in 7 hours. We also know that the width of the strip plowed by the plows is 1.75 ha.

To find the speed, we need to divide the total area plowed by the time taken. Let's perform the calculation:

Speed = Total area plowed / Time taken

Speed = 4.9 ha / 7 hours

Speed = 0.7 ha/hour

Therefore, the tractor was moving at a speed of 0.7 hectares per hour.

Explanation

The given information states that a tractorist plowed 4.9 hectares in 7 hours. This means that the tractor covered an area of 4.9 hectares in a time span of 7 hours. The width of the strip plowed by the plows is given as 1.75 hectares.

To find the speed at which the tractor was moving, we divide the total area plowed (4.9 hectares) by the time taken (7 hours). This gives us a speed of 0.7 hectares per hour.
