Question

В 8 утра от двух пристаней отправились навстречу один другому два теплохода и встретились в 11 ч того же дня . Расстояние между пристанями 210 км. Скорость одного теплохода 34 км/ ч. С какой скоростью шел другой теплоход?

Answer 1

1. 11-8=3( ч)- время движения до встречи.
2. 3*34=102(км)- расстояние, которое проплыл  первый теплоход до встречи
3. 210-102=108(км)- проплыл второй теплоход до встречи
4. 108/3=36(км/ч)- скорость движения второго теплохода.
Ответ: 36км/ч

Answer 2

Problem Analysis

We are given that two steamboats started from two different piers at 8 am and met each other at 11 am on the same day. The distance between the piers is 210 km, and the speed of one of the steamboats is 34 km/h. We need to find 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: Speed = Distance / Time.

The time taken by the first steamboat to travel from its pier to the meeting point is 3 hours (from 8 am to 11 am). The time taken by the second steamboat to travel from its pier to the meeting point is also 3 hours.

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

34 km/h = 210 km / 3 hours (for the first steamboat)

x km/h = 210 km / 3 hours (for the second steamboat)

Simplifying the equation, we find:

34 = 210 / 3

x = 210 / 3

Now, let's calculate the value of x.

Calculation

Using the given values, we can calculate the speed of the second steamboat:

x = 210 / 3

x = 70 km/h

Answer

The second steamboat was traveling at a speed of 70 km/h.

Explanation

The first steamboat was traveling at a speed of 34 km/h, and the second steamboat was traveling at a speed of 70 km/h. Both steamboats started at 8 am and met each other at 11 am, covering a distance of 210 km.
