Question

Карлсон съедает банку варенья за 5 минут , мальш за час а фрекн Бок за полчаса.А) сколько банок (суммарно) съедят они за час? Б) за какое время они съедят одну банку вместе?

Answer 1

За 1 час --15 банок так как карлосон съедает 60:5 = 15 банок , малыш 1 банку , а фрекн Бок 2 банки ( 60:30)

Answer 2

1. 60/5=12 - банок Карлсон съедает,  малыш -1, Бок-2.
Всего 15 банок за час.
2. за одну минуту съедает Карлсон 1/5= 12/60 банки,
  Малыш съест 1/60 банки,  Бок 1/30=2/60 банки.
  За 1 минуту съедят втроём   12/60 +1/60 + 2/60= 15/60. = 1/4 банки.
Значит, целую банку втроём съедят за 4 минуты.

Answer 3

Calculation of the Number of Jars Eaten in One Hour

To calculate the number of jars of jam eaten by each character in one hour, we need to determine their individual eating rates and then add them together.

According to the given information: - Karlsson eats a jar of jam in 5 minutes. - Malish eats a jar of jam in 1 hour (60 minutes). - Freken Bok eats a jar of jam in 30 minutes.

To find out how many jars each character can eat in one hour, we need to convert their eating rates to jars per hour.

Let's start with Karlsson: - Karlsson eats 1 jar in 5 minutes. - To find out how many jars he can eat in 60 minutes (1 hour), we can set up a proportion: - 1 jar / 5 minutes = x jars / 60 minutes - Solving for x, we get: x = (1 jar / 5 minutes) * 60 minutes = 12 jars

Now let's move on to Malish: - Malish eats 1 jar in 60 minutes (1 hour).

Finally, let's calculate Freken Bok's eating rate: - Freken Bok eats 1 jar in 30 minutes.

To find the total number of jars eaten by all three characters in one hour, we simply add up their individual rates: - Karlsson eats 12 jars in one hour. - Malish eats 1 jar in one hour. - Freken Bok eats 2 jars in one hour.

Therefore, the total number of jars eaten by all three characters in one hour is 15 jars.

Calculation of the Time Taken to Eat One Jar Together

To calculate the time taken for all three characters to eat one jar of jam together, we need to determine their combined eating rate.

Let's add up their individual eating rates: - Karlsson eats 1 jar in 5 minutes. - Malish eats 1 jar in 60 minutes (1 hour). - Freken Bok eats 1 jar in 30 minutes.

To find the combined eating rate, we can add up their rates: - 1 jar / 5 minutes + 1 jar / 60 minutes + 1 jar / 30 minutes = x jars / t minutes

To simplify the calculation, let's convert all the rates to jars per minute: - 1 jar / 5 minutes = 0.2 jars per minute - 1 jar / 60 minutes = 0.0167 jars per minute - 1 jar / 30 minutes = 0.0333 jars per minute

Now let's add up the rates: - 0.2 jars per minute + 0.0167 jars per minute + 0.0333 jars per minute = x jars / t minutes

Simplifying further, we get: - 0.25 jars per minute = x jars / t minutes

To find the time taken to eat one jar together, we can set up a proportion: - 0.25 jars per minute = 1 jar / t minutes

Solving for t, we get: - t = (1 jar / 0.25 jars per minute) = 4 minutes

Therefore, it will take all three characters together 4 minutes to eat one jar of jam.

Please note that the calculations are based on the given information and assumptions made.
