Question

Расстояние между двумя пристанями 212 км. От них одновременно навстречу друг другу отплыли два теплохода, которые встретились через 4 ч. Скорость одного теплохода 24км/ч. Найди скорость другого теплохода.

Answer 1

Problem Analysis

We are given that the distance between two ports is 212 km. Two ships set sail from these ports simultaneously and meet each other after 4 hours. The speed of one ship is given as 24 km/h. We need to find the speed of the other ship.

Solution

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

We can use the formula distance = speed × time to solve this problem.

The distance covered by the first ship in 4 hours is 24 km/h × 4 h = 96 km.

Since the two ships are traveling towards each other, the total distance covered by both ships is equal to the distance between the ports, which is 212 km.

Therefore, the distance covered by the second ship in 4 hours is 212 km - 96 km = 116 km.

Now, we can set up an equation to find the speed of the second ship:

116 km = x km/h × 4 h

Simplifying the equation, we get:

x km/h = 116 km / 4 h

Calculating the value, we find:

x km/h = 29 km/h

Therefore, the speed of the other ship is 29 km/h.

Answer

The speed of the other ship is 29 km/h.

Explanation

The first ship covers a distance of 96 km in 4 hours, while the second ship covers a distance of 116 km in the same time. By setting up an equation and solving for the unknown speed, we find that the speed of the second ship is 29 km/h
