Question

Черепаха прошла мимо бревна длиной 15 м за 5 мин 5 сек, а мимо ландыша - за 5 сек. Вычислите скорость черепахи и ее длину.Помогите.Заранее спасибо!

Answer 1

Переводим в секунды 5,5 = 305 секунд
Переводим в см 15м = 1500 см
Скорость 1500/305= 4,9 см/секунду
Если принять, что ландыш шириной 1 см, то длина черепахи: 4,9^5сек = 24,5 см

Но меня смущает отсутствие целых чисел в ответах. Ну и сама задача неоднозначна. Ландыш стоял или лежал?) с постоянной ли скоростью двигалась черепаха или она залюбовалась ландышем и притормозила гонку)). Ну в общем вы поняли....

Answer 2

Calculation of the Turtle's Speed and Length

To calculate the speed and length of the turtle, we need to use the information provided. The turtle passed a log that is 15 meters long in 5 minutes and 5 seconds, and it passed a lily in 5 seconds.

To calculate the turtle's speed, we can use the formula:

Speed = Distance / Time

Let's calculate the turtle's speed:

Speed = 15 meters / (5 minutes + 5 seconds)

To perform the calculation, we need to convert the time to a single unit. Let's convert the 5 minutes to seconds:

Speed = 15 meters / (5 minutes * 60 seconds/minute + 5 seconds)

Now we can calculate the speed:

Speed = 15 meters / (300 seconds + 5 seconds) = 15 meters / 305 seconds

The turtle's speed is approximately 0.049 meters per second.

To calculate the turtle's length, we can use the formula:

Length = Speed * Time

Let's calculate the turtle's length:

Length = 0.049 meters/second * (5 minutes + 5 seconds)

Again, let's convert the 5 minutes to seconds:

Length = 0.049 meters/second * (5 minutes * 60 seconds/minute + 5 seconds)

Now we can calculate the length:

Length = 0.049 meters/second * (300 seconds + 5 seconds) = 0.049 meters/second * 305 seconds

The turtle's length is approximately 14.945 meters.

Please note that these calculations are based on the information provided and assume constant speed throughout the entire distance.
