Question

Жили-были 2 брата – близнеца. Один из них ежедневно спал 1/3 суток, а другой ¼ суток. Дожили они так до 72 – летнего возраста. Сколько лет за это время проспал каждый из них?

Answer 1

Сначала нам необходимо найти сколько суток в 72 годах:

в 1 году- 365 суток

1)365*72=26280суток в 72 годах.

Далее по условию первый спит 1/3 суток,значит за 72 года он проспал

2)26280:3=8760ч он проспал за всю жизнь.

Теперь переведем все в года:

3)8760:365=24 года проспал первый брат.

Аналогично находим для второго:

1)26280:4=6570ч-за всю жизнь проспал второй брат.

2)6570:365=18 лет проспал второй.

Ответ:24года и 18 лет.

 

Answer 2

 Все  просто .

72года делим  на 3(так  как  спал  1/3 суток)= 24  года  спал один   брат .

72 года делим  на 4 (так как спал 1/4 суток) = 18 лет  спал  второй  брат.

Ответ:24 года , 18 лет.

Answer 3

Calculation of Sleeping Time for Each Twin

To determine how many years each twin slept during their 72-year lifespan, we need to calculate the sleeping time for each twin based on the given information.

Let's denote the first twin as Twin A and the second twin as Twin B.

According to the information provided, Twin A slept 1/3 of a day, while Twin B slept 1/4 of a day.

To calculate the sleeping time for each twin, we need to convert the fractions of a day into hours.

Since a day consists of 24 hours, we can calculate the sleeping time for each twin as follows:

- Twin A slept for 1/3 of a day, which is equal to (1/3) * 24 = 8 hours. - Twin B slept for 1/4 of a day, which is equal to (1/4) * 24 = 6 hours.

Therefore, Twin A slept for 8 hours each day, while Twin B slept for 6 hours each day.

Calculation of Total Sleeping Time for Each Twin

To calculate the total sleeping time for each twin over their 72-year lifespan, we need to multiply the daily sleeping time by the number of days in 72 years.

Since there are 365 days in a year, we can calculate the total sleeping time for each twin as follows:

- Twin A slept for 8 hours each day, so the total sleeping time for Twin A over 72 years is 8 hours/day * 365 days/year * 72 years = 210,240 hours. - Twin B slept for 6 hours each day, so the total sleeping time for Twin B over 72 years is 6 hours/day * 365 days/year * 72 years = 157,680 hours.

Therefore, Twin A slept for a total of 210,240 hours over 72 years, while Twin B slept for a total of 157,680 hours over 72 years.

Conclusion

In summary, based on the given information, Twin A slept for 8 hours each day and a total of 210,240 hours over 72 years. Twin B slept for 6 hours each day and a total of 157,680 hours over 72 years.

Please note that the above calculations are based on the information provided and assume a consistent sleeping pattern throughout the entire 72-year lifespan.
