Question

4. Три королевских стражника готовят площадку для крикета: им нужно покрасить 15 розовых кустов, поймать 10 фламинго и свернуть 20 ежей в шары. Первый стражник может за минуту свернуть в шар двух ежей, или поймать одного фламинго, или покрасить Один куст. Второй стражник может за минуту свернуть в шар трёх ежей, или поймать одного фламинго, или покрасить полтора куста. Наконец, третий стражник может за минуту свернуть в шар одного ежа, или поймать двух фламинго, или покрасить два куста. Как им распределить работу, чтобы успеть к началу матча, до которого осталось 10 минут? а) Первый стражник занимается ежами, второй — кустами, третий – фламинго. б) Первый стражник занимается кустами, второй — фламинго, третий — ежами. в) Первый стражник занимается фламинго, второй — ежами, третий — кустами.​

Answer 2

To solve this problem, we need to consider the abilities of each guard and the tasks that need to be completed. Let's break down the information given:

- The first guard can roll two hedgehogs into balls in one minute, catch one flamingo in one minute, or paint one bush. - The second guard can roll three hedgehogs into balls in one minute, catch one flamingo in one minute, or paint one and a half bushes. - The third guard can roll one hedgehog into a ball in one minute, catch two flamingos in one minute, or paint two bushes.

We need to complete the following tasks: - Paint 15 bushes - Catch 10 flamingos - Roll 20 hedgehogs into balls

To determine the most efficient way to distribute the tasks, we need to find the combination of tasks that can be completed in the shortest amount of time.

Let's consider the options:

a) The first guard handles the hedgehogs, the second guard handles the bushes, and the third guard handles the flamingos. - The first guard can roll two hedgehogs into balls in one minute, so it would take them 10 minutes to roll 20 hedgehogs into balls. - The second guard can paint one and a half bushes in one minute, so it would take them 10 minutes to paint 15 bushes. - The third guard can catch two flamingos in one minute, so it would take them 5 minutes to catch 10 flamingos.

In total, it would take 10 minutes for the first guard, 10 minutes for the second guard, and 5 minutes for the third guard, resulting in a total of 25 minutes.

b) The first guard handles the bushes, the second guard handles the flamingos, and the third guard handles the hedgehogs. - The first guard can paint one bush in one minute, so it would take them 15 minutes to paint 15 bushes. - The second guard can catch one flamingo in one minute, so it would take them 10 minutes to catch 10 flamingos. - The third guard can roll three hedgehogs into balls in one minute, so it would take them 7 minutes to roll 20 hedgehogs into balls.

In total, it would take 15 minutes for the first guard, 10 minutes for the second guard, and 7 minutes for the third guard, resulting in a total of 32 minutes.

c) The first guard handles the flamingos, the second guard handles the hedgehogs, and the third guard handles the bushes. - The first guard can catch one flamingo in one minute, so it would take them 10 minutes to catch 10 flamingos. - The second guard can roll two hedgehogs into balls in one minute, so it would take them 10 minutes to roll 20 hedgehogs into balls. - The third guard can paint two bushes in one minute, so it would take them 7.5 minutes to paint 15 bushes.

In total, it would take 10 minutes for the first guard, 10 minutes for the second guard, and 7.5 minutes for the third guard, resulting in a total of 27.5 minutes.

Based on these calculations, option c) The first guard handles the flamingos, the second guard handles the hedgehogs, and the third guard handles the bushes would be the most efficient way to distribute the tasks, as it would take a total of 27.5 minutes to complete all the tasks.

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