Question

В цестерне для полива было 40 т воды. каждый день утром для полива берут 8 т воды,а вечером доливают 4 т воды. через сколько дней цистерна опустеет?

Answer 1

8-4=4т -расход воды ежедневно
40:4=10дней

Answer 2

Calculation of Days until the Cistern is Empty

To calculate the number of days until the cistern is empty, we need to determine how much water is used each day and divide the total amount of water in the cistern by the daily usage.

Given: - Total amount of water in the cistern: 40 tons - Water used for watering in the morning: 8 tons - Water added in the evening: 4 tons

To find out how much water is used each day, we need to add the water used in the morning and subtract the water added in the evening: - Water used each day = Water used in the morning - Water added in the evening - Water used each day = 8 tons - 4 tons = 4 tons

Now, we can calculate the number of days until the cistern is empty: - Number of days = Total amount of water in the cistern / Water used each day - Number of days = 40 tons / 4 tons = 10 days

Therefore, the cistern will be empty after 10 days of watering.

Please note that the above calculation assumes that the water usage remains constant and there are no other factors affecting the water level in the cistern.
