Question

Газовая плита на даче работает 60 часов от малого газового баллона, а от большого баллона она работает 130 часов. Бабушка привезла с собой на дачу один полный большой баллон и один полный малый баллон. Пока бабушка жила на даче, ей пришлось заправлять большой баллон два раза, а малый баллон она заправляла один раз. К отъезду оба баллона оказались пустыми. Сколько часов работала плита у бабушки?

Answer 1

К отъезду оба баллона оказались пустыми, тогда бабушка израсходовала с учетом заправки:

1) 1 + 1 = 2 шт. - малых баллонов

2) 1 + 2 = 3 шт. - больших баллонов

Найдем сколько часов работала плита у бабушки

3) 2 * 60 + 3 * 130 = 120 + 390 = 510 ч

Ответ: 510 ч.

Answer 2

Бабушка израсходовала
Большой баллон 3 шт
Малый - 2
Тогда
130*3+60*2=510 Часов работала плита

Answer 3

Calculating Gas Stove Usage

To calculate the total hours the gas stove worked at the grandmother's dacha, we can use the given information about the working hours of the stove with different gas cylinders.

1. Hours of Operation with Small and Large Cylinders: - The gas stove works for 60 hours with a small gas cylinder and 130 hours with a large gas cylinder.

2. Gas Cylinder Refills: - The grandmother had one full large gas cylinder and one full small gas cylinder when she arrived at the dacha. - She had to refill the large gas cylinder twice and the small gas cylinder once during her stay.

Calculating Total Hours of Operation

To calculate the total hours the gas stove worked at the grandmother's dacha, we can use the information about the working hours with each type of cylinder and the number of refills.

1. Total Hours with Large Cylinder: - The stove works for 130 hours with a full large gas cylinder. - The grandmother refilled the large cylinder twice during her stay. - Therefore, the total hours the stove worked with the large cylinder is: \[130 \text{ hours} \times 3 = 390 \text{ hours}\]

2. Total Hours with Small Cylinder: - The stove works for 60 hours with a full small gas cylinder. - The grandmother refilled the small cylinder once during her stay. - Therefore, the total hours the stove worked with the small cylinder is: \[60 \text{ hours} \times 2 = 120 \text{ hours}\]

Conclusion

The gas stove worked for a total of 510 hours during the grandmother's stay at the dacha.
