Question

От пристани отплыл катер со скоростью 54 километров час вслед за ним сразу отплыл теплоход со скоростью 26 км в час через какое время между ними будет расстояние 76 км

Answer 1

54-26=28км(расстояние между ними)
76:28=через 2.7 часа

Answer 2

Problem Analysis

We are given the information that a boat and a ship have departed from a dock. The boat is traveling at a speed of 54 kilometers per hour, while the ship is traveling at a speed of 26 kilometers per hour. We need to determine the time it takes for the distance between them to be 76 kilometers.

Solution

To find the time it takes for the distance between the boat and the ship to be 76 kilometers, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the difference in speed between the boat and the ship.

Let's calculate the time it takes for the distance between them to be 76 kilometers.

Calculation

The relative speed between the boat and the ship is the difference between their speeds:

Relative Speed = Boat Speed - Ship Speed

Relative Speed = 54 km/h - 26 km/h

Relative Speed = 28 km/h

Now, we can calculate the time it takes for the distance between them to be 76 kilometers:

Time = Distance / Relative Speed

Time = 76 km / 28 km/h

Time ≈ 2.71 hours

Therefore, it will take approximately 2.71 hours for the distance between the boat and the ship to be 76 kilometers.

Answer

The time it takes for the distance between the boat and the ship to be 76 kilometers is approximately 2.71 hours.
