Question

Двое рабочих выполняют некоторую работу за 7 дней при условии, что второй рабочий приступит к ней на два дня позже первого. Если бы ту же работу каждый выполнял в одиночку, то первому понадобилось бы на 4 дня больше, чем второму. За сколько дней каждый рабочий выполнит эту работу?

Answer 1

Problem Analysis

We have two workers who are completing a certain task in 7 days. The second worker starts the task two days after the first worker. If each worker were to complete the task individually, the first worker would take 4 days longer than the second worker. We need to determine how many days it will take each worker to complete the task.

Solution

Let's assume that the first worker takes x days to complete the task. Since the second worker starts two days later, they will take x - 2 days to complete the task.

According to the given information, if each worker were to complete the task individually, the first worker would take 4 days longer than the second worker. Therefore, we can set up the following equation:

x = (x - 2) + 4

Simplifying the equation, we get:

x = x - 2 + 4 x = x + 2

This equation has no solution, which means there is an error in the given information. Please double-check the problem statement or provide additional information to proceed with the calculation.
