Question

2 теплохода движутся навстречу друг другу от 2 пристаней и встретились через 3 часа .Найди расстояние между пристанями если собственная скорость каждого теплохода 32 км в час ,а скорость течения реки равна 2 км час.

Answer 1

1)(32+2)*3=132 км прошёл теплоход ,идущий по реке
2)(32-2)*3=120 км прошёл теплоход, идущий против реки
3)132+120=252 км
или же
3*((32+2)+(32-2))=252
Ответ: расстояние между пристанями 252 км.

Answer 2

1)(32-2)+(32+2)=64(км/ч)скорость теплоходов вместе.
2)64×3=192(км)
Ответ:192 км расстояние между двумя пристанями.

Answer 3

Problem Analysis

We are given that two steamboats are moving towards each other from two different piers and meet after 3 hours. We need to find the distance between the piers given that the speed of each steamboat is 32 km/h and the speed of the river current is 2 km/h.

Solution

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

Let's assume that the distance between the piers is D km.

The first steamboat is moving towards the second steamboat, so its effective speed is the sum of its own speed and the speed of the river current: 32 km/h + 2 km/h = 34 km/h.

The second steamboat is moving towards the first steamboat, so its effective speed is also the sum of its own speed and the speed of the river current: 32 km/h + 2 km/h = 34 km/h.

We are given that the two steamboats meet after 3 hours. Therefore, the total distance covered by both steamboats is equal to the distance between the piers.

Using the formula distance = speed * time, we can write the following equation:

34 km/h * 3 hours + 34 km/h * 3 hours = D km

Simplifying the equation, we get:

68 km/h * 3 hours = D km

204 km = D

Therefore, the distance between the piers is 204 km.

Answer

The distance between the piers is 204 km.
