Question

От пристани отошли одновременно 2 парохода в противоположенных направлениях,через 4 часа расстояние между ними стало 268 км.скорость первого была 35км\ч,найти скорость второго парохода.

Answer 1

1)268:4=67(км/ч)
2)67–35=32(км/ч)V2

Answer 2

1)268:4=67(км/ч)- средняя V удаления пароходов.

2) 67-35=32(км/ч)- V второго парохода.

Ответ: 32 км/ч скорость второго парохода.

Answer 3

Problem Analysis

Two ships depart from a dock simultaneously in opposite directions. After 4 hours, the distance between them is 268 km. The speed of the first ship is 35 km/h. We need to find the speed of the second ship.

Solution

Let's denote the speed of the second ship as x km/h.

After 4 hours, the first ship has traveled a distance of 35 km/h * 4 h = 140 km. The second ship has also traveled for 4 hours at speed x km/h.

The total distance covered by both ships is 140 km + 4x km = 268 km.

Calculating the Speed of the Second Ship

We can now solve for x: 140 km + 4x km = 268 km 4x km = 268 km - 140 km 4x km = 128 km x = 32 km/h

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

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