Question

Пять землекопов за 5 часов выкапывают 5 метров канавы. Сколько землекопов выкопают 100 метров канавы за 100 часов? очень нужен ответ

Answer 1

5м/5ч=1м в час 1м/5=100см/5=20см - 1 землекоп в час100м/0,2м=500./100=5 Ответ: 5 землекопов

Answer 2

Problem Analysis

We are given that five diggers can dig a 5-meter trench in 5 hours. We need to determine how many diggers would be needed to dig a 100-meter trench in 100 hours.

Solution

To solve this problem, we can use the concept of proportionality. If the number of diggers is directly proportional to the length of the trench and the time taken, we can set up a proportion to find the number of diggers needed.

Let's assume that x is the number of diggers needed to dig a 100-meter trench in 100 hours. We can set up the following proportion:

5 diggers / 5 meters = x diggers / 100 meters

Simplifying the proportion, we get:

5/5 = x/100

Cross-multiplying, we get:

5 * 100 = 5 * x

Simplifying further, we find:

500 = 5x

Dividing both sides by 5, we get:

100 = x

Therefore, we need 100 diggers to dig a 100-meter trench in 100 hours.

Conclusion

To dig a 100-meter trench in 100 hours, you would need 100 diggers.
