Question

Два теплохода вышли навстречу друг другу в 8 ч и встретились в 13 ч того же дня В 8 ч расстояние между ними было 290 км Один теплоход плыл со скоростью 28 кмч С какой скоростью плыл другой теплоход

Answer 1

13-8=5 часов теплоходы были в пути 28*5=140 км прошел за 5 часов 1 теплоход 290-140=150 км прошел 2 теплоход 150:5=30 км/час скорость 2 теплохода

Answer 2

1)13-8=5(ч.)
2)28×5=140(км)
3) 290-140=150(км)
4) 150:5=30(км)

Answer 3

Problem Analysis

We are given that two ships set sail towards each other at 8:00 AM and meet at 1:00 PM on the same day. The distance between them at 8:00 AM is 290 km. We are also given that one ship is traveling at a speed of 28 km/h. We need to find the speed of the other ship.

Solution

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

We can calculate the time it takes for the two ships to meet by subtracting the initial time (8:00 AM) from the meeting time (1:00 PM). This gives us a total of 5 hours.

We can use the formula distance = speed × time to calculate the distance traveled by each ship.

For the ship traveling at 28 km/h, the distance traveled is 28 × 5 = 140 km.

For the ship traveling at speed x km/h, the distance traveled is x × 5 km.

Since the ships are traveling towards each other, the sum of the distances traveled by both ships should be equal to the initial distance between them, which is 290 km.

Therefore, we can write the equation:

140 + 5x = 290

Simplifying the equation, we get:

5x = 150

Dividing both sides of the equation by 5, we find:

x = 30

Therefore, the other ship is traveling at a speed of 30 km/h.

Answer

The other ship is traveling at a speed of 30 km/h.
