Question

Цистерна с водой через одну трубу вливается 5 ведер за 12 минут через шланг водой из цистерны поливают сад расходы при этом 40 ведер воды в час через сколько часов опустошается полная цистерна вмещает 60 ведер если труба использоваться одновременно

Answer 1

1) 5:12= 5/12  в/мин    -     скорость вливания воды
2) 40:60= 4/6= 2/3 в/мин  - скорость выливания воды
3) 2/3 - 5/12= 8/12 - 5/12= 3/12= 1/4 в/мин - скорость выливания при одновременном использовании трубы и шланга
4) 60:1/4= 240 мин = 4 часа

Answer 2

Calculating the Time to Empty the Tank

To calculate the time it takes to empty a full tank, we need to consider the rate at which water is being poured into the tank and the rate at which water is being used to water the garden.

According to the information provided, the tank is being filled at a rate of 5 buckets in 12 minutes through one pipe, and the garden is using water at a rate of 40 buckets per hour through another pipe.

Let's calculate the time it takes to empty the tank:

1. Calculate the rate at which water is being poured into the tank through the first pipe: - 5 buckets in 12 minutes - Convert minutes to hours: 12 minutes ÷ 60 minutes/hour = 0.2 hours - Calculate the rate: 5 buckets ÷ 0.2 hours = 25 buckets/hour

2. Calculate the time it takes to empty the tank using the rate at which water is being used by the garden: - 40 buckets per hour

3. Calculate the time to empty the tank: - Divide the tank capacity (60 buckets) by the rate at which water is being used by the garden (40 buckets/hour): - 60 buckets ÷ 40 buckets/hour = 1.5 hours

Therefore, it takes 1.5 hours to empty the full tank if both pipes are used simultaneously.
