Question

Идёт дождь.Под водосточную трубу поставили бочку, в которую входит 300 литров.Каждую минуту в неё вливается 8 литров, а через щель выливается 3 литра воды вминуту.Успеет ли бочка наполниться водой, если дождь шёл 1 час 10 минут?

Answer 1

1) 8 - 3 = 5(л) воды вливается в бочку каждую минуту
2) 1час 19мин = 70 мин.
     5 х 70 = 350(л) воды вольётся в бочку через 1 час 10минут
Ответ: бочка успеет наполнится, потому что емкость бочки 300л, а нальётся в
            неё 350 л .

Answer 2

В 1 часу 60 минут и еще плюс 10 минут=70 минут в 1 часу и 10 минут
Решение:
(8*70)-(3*70)=560-210=350 литров
Успеет, даже будет выливаться

Answer 3

Calculation of Water in the Barrel

To determine if the barrel will be filled with water, we need to calculate the net amount of water that enters the barrel every minute.

The water entering the barrel every minute is 8 liters, and the water leaving the barrel through the gap is 3 liters. Therefore, the net amount of water entering the barrel every minute is 8 liters - 3 liters = 5 liters.

Calculation of Time

The total time the rain has been falling is 1 hour and 10 minutes, which is equivalent to 70 minutes.

To calculate if the barrel will be filled with water, we need to determine the total amount of water that enters the barrel during this time.

The net amount of water entering the barrel every minute is 5 liters. Therefore, the total amount of water that enters the barrel in 70 minutes is 5 liters/minute * 70 minutes = 350 liters.

Comparison with Barrel Capacity

The capacity of the barrel is given as 300 liters.

Since the total amount of water that enters the barrel in 70 minutes is 350 liters, which is greater than the barrel's capacity, the barrel will be filled with water.

Therefore, the barrel will be filled with water if the rain continues for 1 hour and 10 minutes.
