Question

За один вдих людина вдихає приблизно 0,5 л повітря. За хвилину вона робить, в середньому, 15 дихальних рухів. Встанови, скільки літрів повітря проходить через легені 8 людей за 13 годин?   Визнач у м3, враховуючи, що 1м3 = 1000 л.   Відповідь:   37,4 5,9 46,8 56,2 даю 50 балів​

Answer 1

Ответ:

46,8

Объяснение:

1 вд. = 0.5 л

1 хв. = 15 вд.

тоді, за 1 год (60 хв) = 15*60=900 вд.

900вд*0.5л= 450л - 1 людина за 1 год

у нас 13 годин, отже 450вд*13год= 5 850л - вдихає 1 людина за 13 годин

оскільки у нас 8 людей, то 5 850*8= 46 800л

Переведемо в м3:

46 800л:1000л= 46,8м3

Answer 2

To calculate the total volume of air passing through the lungs of 8 individuals in 13 hours, we need to consider the volume of air inhaled per breath and the number of breaths per minute.

Given: - Volume of air inhaled per breath: 0.5 liters - Number of breaths per minute: 15

First, let's calculate the volume of air inhaled per minute by one individual: 0.5 liters/breath * 15 breaths/minute = 7.5 liters/minute

Next, let's calculate the volume of air inhaled per hour by one individual: 7.5 liters/minute * 60 minutes/hour = 450 liters/hour

Now, let's calculate the total volume of air inhaled by one individual in 13 hours: 450 liters/hour * 13 hours = 5850 liters

Since we have 8 individuals, we can multiply the volume inhaled by one individual by 8 to get the total volume of air inhaled by all 8 individuals: 5850 liters * 8 = 46800 liters

To convert liters to cubic meters, we need to divide the volume by 1000 (since 1 cubic meter is equal to 1000 liters): 46800 liters / 1000 = 46.8 cubic meters

Therefore, the total volume of air passing through the lungs of 8 individuals in 13 hours is approximately 46.8 cubic meters.
