Question

Помогите пожалуйста срочно! 20 пунктов за решение!!!За одну секунду самолет пролетает 1/1000 расстояния между городами A и B. Какую часть расстояния самолет пролетит за 10 секунд? Найдите расстояние между городами A и B, если скорость самолета-187 м/сек.

Answer 1

1) за 10 с 1/100 расстояния

2) 187*1000=187000 м=187 км

Answer 2

Problem Analysis

We are given that a plane travels 1/1000th of the distance between cities A and B in one second. We need to find the fraction of the distance the plane will travel in 10 seconds. We are also given that the speed of the plane is 187 m/s.

Solution

To find the fraction of the distance the plane will travel in 10 seconds, we can multiply the fraction of the distance traveled in one second by 10.

Let's calculate the fraction of the distance traveled in one second: 1/1000

Now, let's calculate the fraction of the distance the plane will travel in 10 seconds: (1/1000) * 10 = 1/100

Therefore, the plane will travel 1/100th of the distance between cities A and B in 10 seconds.

To find the distance between cities A and B, we can use the formula: distance = speed * time.

Given that the speed of the plane is 187 m/s and the time is 10 seconds, we can calculate the distance: distance = 187 * 10 = 1870 meters.

Therefore, the distance between cities A and B is 1870 meters.

Conclusion

In summary, the plane will travel 1/100th of the distance between cities A and B in 10 seconds. The distance between cities A and B is 1870 meters.
