Problem:

Два повара должны испечь 174 пирожка. За час работы один повар может испечь 30 пирожков, а другой - 28. За сколько часов работая вместе они испекут все пирожки?

Solution:

To find out how many hours it will take for the two cooks to bake all the pastries together, we need to calculate the combined baking rate of both cooks and divide the total number of pastries by this rate.

Let's calculate the combined baking rate of the two cooks: - The first cook can bake 30 pastries in one hour. - The second cook can bake 28 pastries in one hour.

To find the combined baking rate, we add the individual baking rates of the two cooks: 30 pastries/hour + 28 pastries/hour = 58 pastries/hour.

Now, we can divide the total number of pastries (174) by the combined baking rate (58 pastries/hour) to find the number of hours it will take for the two cooks to bake all the pastries: 174 pastries ÷ 58 pastries/hour = 3 hours.

Therefore, it will take the two cooks working together 3 hours to bake all 174 pastries.
