Question

От первой пристани одновременно в противоположных направлениях отплыли два катера через 3 часа расстояние между ними стало равно 168 километров Найдите скорость второго катера если известно что скорость первого катера составляет 25 километров в час

Answer 1

168÷3=56км/ч
56-25=31км/ч
ответ 31 км / ч скорость 2 катера

Answer 2

Problem Analysis

We are given that two boats departed from the same dock in opposite directions. After 3 hours, the distance between them became 168 kilometers. We need to find the speed of the second boat, given that the speed of the first boat is 25 kilometers per hour.

Solution

Let's assume the speed of the second boat is v kilometers per hour.

The distance covered by the first boat in 3 hours is 25 * 3 = 75 kilometers.

The distance covered by the second boat in 3 hours is v * 3 kilometers.

The total distance between the two boats after 3 hours is the sum of the distances covered by both boats:

75 + v * 3 = 168 kilometers.

To find the value of v, we can rearrange the equation:

v * 3 = 168 - 75.

Simplifying the equation:

v * 3 = 93.

Dividing both sides of the equation by 3:

v = 93 / 3.

Therefore, the speed of the second boat is 31 kilometers per hour.

Answer

The speed of the second boat is 31 kilometers per hour.
