Question

Спутник пролетает 84000 км за 3 ч.За какое время он пролетит 420000км,если будет двигадться с той же скоростью? Какое расстояние Спутник пролетит за 9 ч ,если будет двигаться с той же скоростью?

Answer 1

                          Задача
1) 84000:3=28000 (км/ч)-скорость спутника
2) 420000:28000=15 (ч)-время
3) 28000*9=252000 (км)-расстояние
   Ответ: 252000 км, за 15 часов
    

Answer 2

84000/3=28000(км/ч) скор спутника
420000/28000=15(ч)
28000*9=252000(км)

Answer 3

To answer your questions, let's calculate the time it takes for the satellite to travel a certain distance and the distance it will cover in a given time period.

Time taken to travel 420,000 km:

If the satellite travels 84,000 km in 3 hours, we can calculate its speed by dividing the distance by the time: 84,000 km / 3 hours = 28,000 km/h.

To find out how long it will take for the satellite to travel 420,000 km at the same speed, we can use the formula: time = distance / speed.

Plugging in the values, we get: time = 420,000 km / 28,000 km/h = 15 hours.

Therefore, the satellite will take 15 hours to travel 420,000 km at the same speed. (Answer: 15 hours).

Distance covered in 9 hours:

If the satellite travels at a speed of 28,000 km/h, we can calculate the distance it will cover in 9 hours by multiplying the speed by the time: 28,000 km/h * 9 hours = 252,000 km.

Therefore, the satellite will cover a distance of 252,000 km in 9 hours at the same speed. (Answer: 252,000 km).
