Question

От пристани волгоград отошли одновременно в противоположных направлениях два теплохода.Через 4ч расстояние между ними стало 268км.Скорость первого теплохода 35км/ч.Найди скорость второго теплохода

Answer 1

268÷4=67 км/ч скорость удаления
67-35=32 км/ч скорость 2 теплохода

Answer 2

Problem Analysis

We are given that two ships departed from the Volgograd pier simultaneously in opposite directions. After 4 hours, the distance between them was 268 km. We are also given the speed of the first ship, which is 35 km/h. We need to find the speed of the second ship.

Solution

Let's assume the speed of the second ship is x km/h.

The distance covered by the first ship in 4 hours is 35 km/h * 4 h = 140 km.

The distance covered by the second ship in 4 hours is x km/h * 4 h = 4x km.

The total distance between the two ships after 4 hours is the sum of the distances covered by each ship:

140 km + 4x km = 268 km

To find the value of x, we can solve this equation:

140 km + 4x km = 268 km

Subtracting 140 km from both sides of the equation:

4x km = 268 km - 140 km

4x km = 128 km

Dividing both sides of the equation by 4:

x km = 128 km / 4

x km = 32 km/h

Therefore, the speed of the second ship is 32 km/h.

Answer

The speed of the second ship is 32 km/h.
