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 км\ч.с какой скоростью плыл другой теплоход.

Answer 1

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

Answer 2

Problem Analysis

We are given that two ships set out 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 was 290 km. One of the ships was traveling at a speed of 28 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 calculate the time it took for the ships to meet by subtracting the starting time from the meeting time: Time taken = 13:00 - 8:00 = 5 hours.

We can calculate the distance traveled by the ship traveling at 28 km/h using the formula: Distance = Speed × Time.

The distance traveled by the ship traveling at 28 km/h is: Distance = 28 km/h × 5 hours = 140 km.

Since the total distance between the ships at 8:00 AM was 290 km, we can find the distance traveled by the other ship using the formula: Distance = Total distance - Distance traveled by the ship traveling at 28 km/h.

Substituting the values, we get: Distance = 290 km - 140 km = 150 km.

Now, we can calculate the speed of the other ship using the formula: Speed = Distance / Time.

Substituting the values, we get: Speed = 150 km / 5 hours = 30 km/h.

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

Answer

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