Question

Теплоход рассчитан на 450пассажиров и 30 членов команды. одна спасательная шлюпка может вместить 90человек. какое наименьшее количество шлюпок потребуется для того, чтобы в случае необходимости разместить а них всех пассажиров и членов команды?

Answer 1

450 + 30 = 480 человек всего
480 : 90 = 5 (ост.30)
Ответ : Для того чтобы разместить всех пассажиров и членов команды потребуется 6 шлюпок

Answer 2

Calculating the Number of Required Lifeboats

To determine the minimum number of lifeboats required to accommodate all passengers and crew in case of an emergency, we can use the information provided:

- The ship is designed for 450 passengers and 30 crew members. - Each lifeboat can accommodate 90 people.

To find the minimum number of lifeboats needed, we can use the following calculation:

Total number of people to accommodate = Number of passengers + Number of crew members

Total number of people to accommodate = 450 passengers + 30 crew members

Total number of people to accommodate = 480 people

Minimum number of lifeboats needed = Total number of people to accommodate / Capacity of each lifeboat

Minimum number of lifeboats needed = 480 people / 90 people per lifeboat

Minimum number of lifeboats needed = 5.33

Since we cannot have a fraction of a lifeboat, we would need to round up to the nearest whole number. Therefore, the minimum number of lifeboats required to accommodate all passengers and crew in case of an emergency is 6.

This calculation ensures that there are enough lifeboats to safely evacuate all individuals in the event of an emergency at sea.
