Question

У орла время насиживания яиц составляет 75% времени выкармливания птенцов а время обучения орлят летать после их вылета из гнезда составляет 35% времени выкармливания птенцов .сколько времени продолжается время выкармливанмя, если первый период больше третьего на 24 дня?

Answer 1

24 дня соответствуют 75-35=40% от времени выкармливания. То есть 24 соответствует 0,4*tв⇒tв=24/0,4=60 дней.

Ответ: 60 дней.

Answer 2

Duration of Incubation and Nestling Period for Eagles

The incubation period for eagles, which is the time during which they sit on their eggs to keep them warm, constitutes 75% of the time spent feeding their chicks. The time it takes for eaglets to learn to fly after leaving the nest makes up 35% of the time spent feeding the chicks.

To calculate the duration of the feeding period, we need to determine the difference between the first and third periods. According to the information provided, the first period (incubation) is longer than the third period (time spent teaching eaglets to fly) by 24 days.

Let's denote the duration of the feeding period as "x" days.

The first period (incubation) is 75% of the feeding period, which is 0.75x days.

The third period (teaching eaglets to fly) is 35% of the feeding period, which is 0.35x days.

According to the given information, the first period is longer than the third period by 24 days.

Therefore, we can set up the following equation:

0.75x - 0.35x = 24

Simplifying the equation:

0.4x = 24

Dividing both sides of the equation by 0.4:

x = 60

Therefore, the duration of the feeding period, which includes both incubation and teaching eaglets to fly, is 60 days.
