Question

Теплоход и катер отошли одновременно от одной пристани в противоположных направлениях скорость теплохода 550 метров в минуту скорость катера на 200 метров в минуту меньше Какое расстояние будет между ними через 3 часа

Answer 1

550+200=750м/мин-скорость отдаления
750*3*60=135000м
135000/1000=135км

или
550/1000=0,55км/мин
0,55*60=33км/ч-скорость теплохода

200/1000=0,2км/мин
0,2*60=12км/ч-скорость катера

33+12=45км/ч-скорость отдаления
45*3=135км

Answer 2

Problem Analysis

We are given that a ship and a boat depart simultaneously from the same dock in opposite directions. The ship has a speed of 550 meters per minute, while the boat has a speed 200 meters per minute slower than the ship. We need to find the distance between them after 3 hours.

Calculation

To find the distance between the ship and the boat after 3 hours, we need to calculate the distance each of them has traveled in that time.

The ship's speed is given as 550 meters per minute, so in 3 hours (180 minutes), the ship will have traveled a distance of: 550 meters/minute * 180 minutes = 99,000 meters.

The boat's speed is 200 meters per minute slower than the ship, so its speed is: 550 meters/minute - 200 meters/minute = 350 meters/minute.

Therefore, in 3 hours (180 minutes), the boat will have traveled a distance of: 350 meters/minute * 180 minutes = 63,000 meters.

Answer

After 3 hours, the ship and the boat will be 99,000 meters apart.
