Question

Два теплохода вышли одновременно от одной пристани в одном и том же направлении. Через 30 минут растояноие между ними было 3 км .Наити скорость втрого теплохода,если скорость первого меньше скорости второго и равняется 250 м в мин

Answer 1

1)250*30 = 7500 (м)первый теплоход за 30 мин

2)7,5+3 =10,5 (км) 2 теплоход

Ответ10500 м : 30 мин=350 км/мин:

Answer 2

1)250*30 = 7500 (м)-первый теплоход за 30 мин

2)7,5+3 =10,5 (км)-теплоход

Ответ,350 км/мин

Answer 3

Problem Analysis

We have two boats that left the same dock at the same time and in the same direction. After 30 minutes, the distance between them is 3 km. We need to find the speed of the second boat, given that the speed of the first boat is 250 m/min and is slower than the second boat.

Solution

Let's assume the speed of the second boat is x m/min.

After 30 minutes, the first boat has traveled a distance of 250 m/min * 30 min = 7500 m.

Let's calculate the distance traveled by the second boat in 30 minutes. Since the distance between the two boats is 3 km = 3000 m, the second boat has traveled a distance of 3000 m + 7500 m = 10500 m.

Therefore, the speed of the second boat is 10500 m / 30 min = 350 m/min.

Conclusion

The speed of the second boat is 350 m/min.
