Question

Один рабочий выполнит заказ за 7 часов. сколько таких заказов выполнят двое рабочих за 14 часов работая вместе,если они работают с одинаковой скоростью?

Answer 1

14:7 +14:7 = 4 заказа выполнили двое рабочих за 14 часов

Answer 2

Problem Analysis

We are given that one worker can complete an order in 7 hours. We need to determine how many orders two workers can complete in 14 hours if they work at the same speed.

Solution

If one worker can complete an order in 7 hours, it means that the rate at which the worker completes the order is 1/7 orders per hour.

Let's assume that two workers can complete x orders in 14 hours. Since they are working at the same speed, each worker will complete x/2 orders in 14 hours.

Now, we can set up the equation:

x/2 orders per hour * 14 hours = x orders

Simplifying the equation:

(x/2) * 14 = x

Solving for x:

14x/2 = x

Multiplying both sides by 2:

14x = 2x

Subtracting 2x from both sides:

14x - 2x = 0

12x = 0

Dividing both sides by 12:

x = 0

Therefore, two workers will not be able to complete any orders in 14 hours if they work at the same speed.

Answer

Two workers will not be able to complete any orders in 14 hours if they work at the same speed.
