Question

Теплоход за 7ч проходит такой же путь,как катер за 4 часа.Найдите скорость теплохода,если она меньше скорось катера в 24 км/ч

Answer 1

Пишите, если что не так.

Answer 2

Пусть х-скорость теплохода, тогда скорость катера равна х+24

По условию 7х=4(х+24)  3х=96  х=32 км/ч - скорость теплохода  

                                                     у=32+24=56км/ч - скорость катера 

Answer 3

Problem Analysis

We are given that a boat travels the same distance in 7 hours as a speedboat does in 4 hours. We need to find the speed of the boat, given that the speed of the speedboat is 24 km/h.

Solution

Let's assume the distance traveled by both the boat and the speedboat is d kilometers.

We can use the formula speed = distance / time to find the speed of each vehicle.

For the boat: - Distance = d kilometers - Time = 7 hours

For the speedboat: - Distance = d kilometers - Time = 4 hours

Let's calculate the speed of the boat and the speedboat:

Speed of the boat = Distance / Time = d / 7 km/h

Speed of the speedboat = Distance / Time = d / 4 km/h

Given that the speed of the speedboat is 24 km/h, we can set up the following equation:

d / 4 = 24

To find the value of d, we can multiply both sides of the equation by 4:

d = 24 * 4 = 96 kilometers

Now that we know the distance, we can find the speed of the boat:

Speed of the boat = d / 7 = 96 / 7 ≈ 13.71 km/h

Therefore, the speed of the boat is approximately 13.71 km/h.

Answer

The speed of the boat is approximately 13.71 km/h.
