Question

От двух пристаней одновременно навстречу друг другу отошли 2 катера . Скорость первого 25 км/ч и он прошол до встречи 125 км. Второй катер прошёл до встречи 150 км какова его скорость?

Answer 1

1)125/25=5(ч)
2)150/5=30(км/ч)
Ответ:30 км/ч.

Answer 2

1)150:(125:5)=30(км/ч)-скорость второго катера 

Answer 3

Problem Analysis

We have two boats that start from different points and move towards each other. The first boat has a speed of 25 km/h and travels a distance of 125 km before they meet. The second boat travels a distance of 150 km before they meet. We need to find the speed of the second boat.

Solution

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

To find the speed of the second boat, we can use the formula:

Speed = Distance / Time

Since both boats start at the same time and meet each other, the time taken by both boats to meet is the same. Let's call this time t.

For the first boat: Speed of the first boat = 25 km/h Distance traveled by the first boat = 125 km

For the second boat: Speed of the second boat = x km/h Distance traveled by the second boat = 150 km

Using the formula, we can set up the following equations:

25 = 125 / t (Equation 1) x = 150 / t (Equation 2)

To solve these equations, we can eliminate the variable t by cross-multiplying:

25 * t = 125 (Equation 3) x * t = 150 (Equation 4)

From Equation 3, we can solve for t:

t = 125 / 25 = 5 hours

Substituting the value of t into Equation 4, we can solve for x:

x * 5 = 150

x = 150 / 5 = 30 km/h

Therefore, the speed of the second boat is 30 km/h.

Answer

The speed of the second boat is 30 km/h.
