Calculation of Travel Time

To calculate the travel time of the ship from Kyiv to Kherson, we can use the information provided. According to the given information, the ship takes 4 days to travel from Kherson to Kyiv and 1 day less to travel from Kyiv to Kherson.

Let's assume that the ship travels at a constant speed throughout the journey. Since the ship takes 4 days to travel from Kherson to Kyiv, we can divide the total travel time by the number of days to find the average speed of the ship.

The average speed of the ship can be calculated as follows:

Average Speed = Total Distance / Total Time

Since the distance between Kherson and Kyiv is the same in both directions, we can assume that the total distance traveled is constant. Therefore, we can use the average speed to calculate the travel time from Kyiv to Kherson.

Let's calculate the average speed of the ship:

Average Speed = Total Distance / Total Time

Using the given information, we can set up the following equation:

Average Speed = Total Distance / 4 days

Now, we know that the ship takes 1 day less to travel from Kyiv to Kherson. Therefore, the travel time from Kyiv to Kherson can be calculated as:

Travel Time from Kyiv to Kherson = Total Distance / (Average Speed + 1)

Let's substitute the values and calculate the travel time from Kyiv to Kherson:

Travel Time from Kyiv to Kherson = Total Distance / (Total Distance / 4 + 1)

Simplifying the equation:

Travel Time from Kyiv to Kherson = 4 / (4 + 1)

Calculating the value:

Travel Time from Kyiv to Kherson = 4 / 5 = 0.8 days

Therefore, the ship takes approximately 0.8 days to travel from Kyiv to Kherson.
