Question

Бассейн имеет размеры 12 м на 25 м рабочий плиточник выкладывает плиткой 3 кв м в день сколько дней нужно рабочему чтобы выложить плиткой пол в бассейне?За сколько времени выполнит эту работу бригада из 5 рабочих при условии что они работают с одинаковой скоростью? две бригады полнили эту работу за 12 дней одна бригада выкладывала 14 кв м в день какова производительность второй бригады?

Answer 1

1.найдем площадь бассейна 12*25=300кв.м. площадь бассейна.

2.найдем сколько дней понадовится  300/3=100 дней понадовится  рабочему чтобы выложить плиткой пол в бассейне

Answer 2

Calculation of the Time Required for a Single Worker to Tile the Pool

To calculate the time required for a single worker to tile the pool, we need to determine the total area of the pool and the tiling rate of the worker.

The pool has dimensions of 12 meters by 25 meters Therefore, the total area of the pool is:

Total Area of the Pool = Length × Width = 12 m × 25 m = 300 square meters

The worker can lay 3 square meters of tiles per day To calculate the time required for a single worker to tile the pool, we divide the total area of the pool by the tiling rate:

Time Required for a Single Worker = Total Area of the Pool / Tiling Rate = 300 square meters / 3 square meters per day = 100 days

Therefore, it would take a single worker 100 days to tile the entire pool.

Calculation of the Time Required for a Brigade of 5 Workers to Tile the Pool

To calculate the time required for a brigade of 5 workers to tile the pool, we divide the total area of the pool by the combined tiling rate of the brigade.

The total area of the pool is 300 square meters, as calculated earlier.

Since the brigade consists of 5 workers, and each worker has a tiling rate of 3 square meters per day, the combined tiling rate of the brigade is:

Combined Tiling Rate of the Brigade = Number of Workers × Tiling Rate per Worker = 5 workers × 3 square meters per day = 15 square meters per day

To calculate the time required for the brigade to tile the pool, we divide the total area of the pool by the combined tiling rate:

Time Required for the Brigade = Total Area of the Pool / Combined Tiling Rate of the Brigade = 300 square meters / 15 square meters per day = 20 days

Therefore, it would take a brigade of 5 workers 20 days to tile the entire pool.

Calculation of the Productivity of the Second Brigade

Given that two brigades completed the tiling work in 12 days, and one brigade had a tiling rate of 14 square meters per day, we can calculate the productivity of the second brigade.

Let's assume the productivity of the second brigade is represented by X square meters per day.

The total area of the pool is 300 square meters, as calculated earlier.

The first brigade had a tiling rate of 14 square meters per day, and they worked for 12 days. Therefore, the area tiled by the first brigade is:

Area Tiled by the First Brigade = Tiling Rate of the First Brigade × Number of Days = 14 square meters per day × 12 days = 168 square meters

The area tiled by the second brigade can be calculated by subtracting the area tiled by the first brigade from the total area of the pool:

Area Tiled by the Second Brigade = Total Area of the Pool - Area Tiled by the First Brigade = 300 square meters - 168 square meters = 132 square meters

To calculate the productivity of the second brigade, we divide the area tiled by the second brigade by the number of days they worked:

Productivity of the Second Brigade = Area Tiled by the Second Brigade / Number of Days = 132 square meters / 12 days = 11 square meters per day

Therefore, the productivity of the second brigade is 11 square meters per day.

In summary: - It would take a single worker 100 days to tile the entire pool. - It would take a brigade of 5 workers 20 days to tile the entire pool. - The productivity of the second brigade is 11 square meters per day.
