Question

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

Answer 1

3 ч - 84000
Х ч - 420000
(прямая пропорция)
Х=3*420000/84000=30/2 часа (15)
3 ч - 84000
9 ч - Х
(прямая пропорция)
Х=9*84000/3=84000*3=252000

Answer 2

84000/3=28000 км спутник пролетает за час
420000/28000=15 за 15 часов спутник пролетит 420000 км
84000*3=252000 км спутник пролетит за 9 часов

Answer 3

To find the answers to your questions, let's calculate the speed of the satellite first. We know that the satellite travels 84,000 km in 3 hours. To find the speed, we divide the distance traveled by the time taken:

Speed = Distance / Time

Speed = 84,000 km / 3 hours

Speed = 28,000 km/h

Now, let's use this speed to answer your questions:

1. How long will it take for the satellite to travel 420,000 km at the same speed?

To find the time taken, we can rearrange the formula:

Time = Distance / Speed

Time = 420,000 km / 28,000 km/h

Time = 15 hours

Therefore, it will take the satellite 15 hours to travel 420,000 km at the same speed.

2. How far will the satellite travel in 9 hours at the same speed?

Using the same formula, we can calculate the distance:

Distance = Speed * Time

Distance = 28,000 km/h * 9 hours

Distance = 252,000 km

Therefore, the satellite will travel 252,000 km in 9 hours at the same speed.

I hope this helps! Let me know if you have any further questions.
