Question

Хочу я купить сапоги – скороходы, Ходить в скороходах отлично в походы: Шагнул один шаг – и проделал семь миль. Обгонишь автобус, автомобиль… За час не спеша обойдешь вокруг света, Догнать тебя сможет только ракета! Приняв 1 милю примерно за 1,6 км, длительность шага за 1с, а длину эква-тора за 40000км, рассчитайте, действительно ли можно обойти всю Землю за один час.

Answer 1

40000:1,6=25000с.

Не сможет.

Answer 2

Can the Earth be Circumnavigated in One Hour?

To determine whether it is possible to circumnavigate the Earth in one hour, we need to calculate the time it would take to travel around the Earth and compare it to one hour.

Let's start by calculating the circumference of the Earth. The equatorial circumference of the Earth is approximately 40,075 kilometers [[1]].

Next, we need to determine the duration of each step and the number of steps required to cover the entire distance around the Earth.

According to the information provided, one step covers a distance of 7 miles, which is approximately 11.26 kilometers. Assuming a step duration of 1 second, we can calculate the number of steps required to cover the Earth's circumference.

Number of steps = Circumference of Earth / Distance covered in one step Number of steps = 40,075 km / 11.26 km ≈ 3,560

Therefore, it would take approximately 3,560 steps to cover the entire distance around the Earth.

Now, let's calculate the time required to complete these steps.

Time required = Number of steps * Duration of each step Time required = 3,560 steps * 1 second ≈ 3,560 seconds

Since there are 60 seconds in a minute and 60 minutes in an hour, we can convert the time required to hours.

Time required in hours = Time required / (60 * 60) Time required in hours = 3,560 seconds / (60 * 60) ≈ 0.99 hours

Based on these calculations, it would take approximately 0.99 hours, or approximately 59.4 minutes, to circumnavigate the Earth using the given step distance and duration.

Therefore, it is not possible to circumnavigate the Earth in one hour based on the provided information.

Please note that these calculations are based on the assumptions provided in the question. The actual time required to circumnavigate the Earth may vary depending on factors such as the speed of travel, terrain, and other variables.

I hope this answers your question! Let me know if you have any further queries.
