Question

На одном ткацком станке за 1 ч вырабатывается 3,45 м ткани. Сколько метров ткани можно выработать за 7 часов, если ткачиха одновременно обслуживает 2 станка?

Answer 1

1) 3,45 * 7 = 24,15 (м) на одном станке за 7 часов.

2) 24,15 * 2 = 48,3 (м) на 2 станках за 7 часов.

Ответ: 48,3 м 

Answer 2

Calculation of Fabric Produced in 1 Hour

According to the given information, one weaving machine produces 3.45 meters of fabric in 1 hour.

Calculation of Fabric Produced in 7 Hours

To calculate the total fabric produced in 7 hours, we need to consider that the weaver is simultaneously operating 2 machines.

Since each machine produces 3.45 meters of fabric in 1 hour, the total fabric produced by both machines in 1 hour is:

2 machines * 3.45 meters/machine = 6.9 meters

Therefore, in 7 hours, the weaver can produce:

7 hours * 6.9 meters/hour = 48.3 meters

So, the weaver can produce 48.3 meters of fabric in 7 hours when simultaneously operating 2 machines.
