Question

Упражнения для повторения 612. Скорость космического корабля «Восток», на котором Юрий Гага- рин совершил свой полёт, равна 8 км/с. 1) За сколько минут он про- летал 960 км? 2) Какое расстояние он пролетал за 1 ч?

Answer 1

Пошаговое объяснение:

8×60=480км/м

960÷480=2( минуты)- за столько он пролнтал 960 км

480×60=28800(км.)- за час

Answer 2

Exercise 612: Speed of the Vostok Spacecraft

The speed of the Vostok spacecraft, on which Yuri Gagarin made his historic flight, is given as 8 km/s. Let's calculate the answers to the following questions:

1) How many minutes did it take for the spacecraft to travel 960 km? 2) How far did the spacecraft travel in 1 hour?

To answer these questions, we can use the formula:

Distance = Speed × Time

Let's calculate the answers step by step:

1) To find the time taken to travel 960 km, we need to rearrange the formula to solve for time:

Time = Distance / Speed

Substituting the given values:

Time = 960 km / 8 km/s

Calculating the result:

Time = 120 seconds

To convert seconds to minutes, we divide by 60:

Time = 120 seconds / 60 = 2 minutes

Therefore, it took the spacecraft 2 minutes to travel 960 km.

2) To find the distance traveled in 1 hour, we can directly use the formula:

Distance = Speed × Time

Substituting the given values:

Distance = 8 km/s × 1 hour

To convert hours to seconds, we multiply by 3600:

Distance = 8 km/s × 1 hour × 3600 seconds/hour

Calculating the result:

Distance = 8 km/s × 3600 seconds = 28,800 km

Therefore, the spacecraft traveled a distance of 28,800 km in 1 hour.

Please note that the calculations provided here are based on the given information and may not account for factors such as acceleration or deceleration during the flight.
