Question

Помогите с задачей. От двух пристаней,расстояние между которыми 900 км,вышли два теплохода. Они встретились через 12 часов. Скорость одного теплохода 35 км/ч. Определите скорость другого теплохода.

Answer 1

Problem Analysis

We are given that two steamboats started from two different piers and met each other after 12 hours. The distance between the piers is 900 km, and the speed of one steamboat is 35 km/h. We need to determine the speed of the other steamboat.

Solution

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

We can use the formula distance = speed × time to solve this problem. The distance traveled by the first steamboat in 12 hours is 35 km/h × 12 h = 420 km.

Since the two steamboats met each other, the sum of the distances traveled by both steamboats should be equal to the total distance between the piers, which is 900 km.

Therefore, the distance traveled by the second steamboat is 900 km - 420 km = 480 km.

Now we can set up the equation:

480 km = x km/h × 12 h

To find the value of x, we can divide both sides of the equation by 12:

480 km / 12 h = x km/h

Simplifying the equation, we get:

40 km/h = x km/h

Therefore, the speed of the other steamboat is 40 km/h.

Answer

The speed of the other steamboat is 40 km/h.
