Question

Теплоход и катер вышли одновременно навстречу друг другу из двух портов расстояние между которыми 300 километров. Скорость кактера 40км\ч. Узнай скорость теплохода, если он встретился с катером через три часа.

Answer 1

1) 300÷3=100(км/ч) скорость катера и теплохода.
2)100-40=60(км/ч)скорость теплохода.

Answer 2

1)40×3=120 (км) проехал катер.
2)300-120=180 (км) проплыл теплоход.
3)180:3=60(км в час)
Ответ скорость теплохода 60 км в час.

Answer 3

Problem Analysis

We have a scenario where a boat and a motorboat are traveling towards each other from two different ports. The distance between the ports is 300 kilometers. The speed of the motorboat is given as 40 km/h. We need to find the speed of the boat if they meet after three hours.

Solution

To find the speed of the boat, we can use the formula: distance = speed × time.

Let's assume the speed of the boat is x km/h. The boat and the motorboat are traveling towards each other, so their combined speed is the sum of their individual speeds.

The motorboat's speed is given as 40 km/h, and they meet after three hours. Therefore, the distance covered by the motorboat in three hours is 40 km/h × 3 hours = 120 km.

Since the total distance between the ports is 300 kilometers, the boat must have covered the remaining distance of 300 km - 120 km = 180 km in three hours.

Now we can set up the equation:

180 km = x km/h × 3 hours

To find the value of x, we can rearrange the equation:

x km/h = 180 km / 3 hours

Simplifying the equation:

x km/h = 60 km/h

Therefore, the speed of the boat is 60 km/h.

Answer

The speed of the boat is 60 km/h.
