Question

помогите решить задачу. Два теплохода отошли одновременно от двух пристаней,расстояние между которыми 4500 метров,в противоположенных направлениях.Скорость одного теплохода 550м/мин ,а скорость другого -на 150 м/мин меньше.Какое расстояние будет между ними через 3 часа?

Answer 1

550-150=400м/мин скорость другого теплохода

1час-60мин, 3час 180минут

550*180=99000метров прошел первый теплоход

400*180=72000 метров прошел второй теплоход

4500+99000+72000=175500метров

Ответ: 175500 метров растояние межу двумя теплоходами

Answer 2

550-150=400м/мин скорость второго теплохода

550+400=950 м /мин скорость их удаления

1 ч=60 мин

3 ч=180 мин

950*180=171000 м пройдут вдвоем за 3 часа

4500+171000=175500 м =175 км 500 м

Ответ: 175 км 500 м

Answer 3

Problem Analysis

We have two boats that depart simultaneously from two different piers, with a distance of 4500 meters between them. The speed of one boat is 550 m/min, while the speed of the other boat is 150 m/min less than that. We need to calculate the distance between the two boats after 3 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by each boat after 3 hours: - Boat 1: speed = 550 m/min, time = 3 hours = 180 minutes - Distance traveled by Boat 1 = 550 m/min × 180 min = 99,000 meters - Boat 2: speed = 550 m/min - 150 m/min = 400 m/min, time = 3 hours = 180 minutes - Distance traveled by Boat 2 = 400 m/min × 180 min = 72,000 meters

Now, let's calculate the distance between the two boats after 3 hours: - Distance between the two boats = Distance traveled by Boat 1 + Distance traveled by Boat 2 - Distance between the two boats = 99,000 meters + 72,000 meters = 171,000 meters

Therefore, the distance between the two boats after 3 hours will be 171,000 meters.

Conclusion

After 3 hours, the distance between the two boats will be 171,000 meters.
