Question

В 8 часов утра от двух пристаней отправились навстречу один другому два теплохода и встретились в 11 ч. того же утра. Растояние между пристанями 210 км. Скорость одного теплохода 34 км/ч С какой скоростью щёл другой теплоход? 1) Сколько часов до встречи был в пути каждый теплоход? 2) Сколько км. до встречи прошёл теплоход, скорость которого 34 км/ч 3) Сколько км. до встречи прошёл другой теплоход?

Answer 1

1)11-8=3 часа время на весь путь

2)210:3=70 км/ч скорость сближения

3)70-34=36км/ч скорость 2 теплохода

4)3*34=102 км проплыл 1 теплоход  (2?)

5)36*3=108 км проплыл 2 теплоход  (3?)

Answer 2

Given Information:

- Two steamboats departed from two different piers at 8:00 am and met each other at 11:00 am on the same morning. - The distance between the piers is 210 km. - The speed of one steamboat is 34 km/h.

Calculating the Speed of the Other Steamboat:

To find the speed of the other steamboat, we can use the formula: Speed = Distance / Time.

Since the two steamboats met each other at 11:00 am, they were in motion for 3 hours (from 8:00 am to 11:00 am).

Let's calculate the speed of the other steamboat: Speed = Distance / Time = 210 km / 3 hours = 70 km/h.

Therefore, the other steamboat was traveling at a speed of 70 km/h.

Calculating the Time Each Steamboat Spent in Transit:

To calculate the time each steamboat spent in transit, we can use the formula: Time = Distance / Speed.

1) Time spent by the steamboat with a speed of 34 km/h: Time = Distance / Speed = 210 km / 34 km/h ≈ 6.18 hours.

2) Time spent by the steamboat with a speed of 70 km/h: Time = Distance / Speed = 210 km / 70 km/h = 3 hours.

Therefore, the steamboat with a speed of 34 km/h spent approximately 6.18 hours in transit, while the steamboat with a speed of 70 km/h spent 3 hours in transit.

Calculating the Distance Traveled by Each Steamboat:

To calculate the distance traveled by each steamboat, we can use the formula: Distance = Speed × Time.

1) Distance traveled by the steamboat with a speed of 34 km/h: Distance = Speed × Time = 34 km/h × 6.18 hours ≈ 210 km.

2) Distance traveled by the steamboat with a speed of 70 km/h: Distance = Speed × Time = 70 km/h × 3 hours = 210 km.

Therefore, both steamboats traveled approximately 210 km before meeting each other.

In summary: 1) The steamboat with a speed of 34 km/h spent approximately 6.18 hours in transit and traveled approximately 210 km. 2) The steamboat with a speed of 70 km/h spent 3 hours in transit and also traveled approximately 210 km.
