ответ:через 6 часов они встретятся

Answer 3

To find out how many hours it will take for the two ships to be 360 km apart, we can use the formula:

Distance = Speed x Time

Let's assign variables to the given information: - Speed of the first ship (Ship A) = 28 km/h - Speed of the second ship (Ship B) = 32 km/h - Distance between the two ships = 360 km - Time taken = unknown (let's call it 't')

Using the formula, we can set up two equations:

Distance traveled by Ship A = Speed of Ship A x Time taken Distance traveled by Ship B = Speed of Ship B x Time taken

Substituting the given values, we get:

28t = Distance traveled by Ship A 32t = Distance traveled by Ship B

Since the two ships are moving in opposite directions, the distance between them is the sum of the distances traveled by each ship:

Distance between the two ships = Distance traveled by Ship A + Distance traveled by Ship B

Substituting the equations for the distances traveled by each ship, we have:

360 = 28t + 32t

Simplifying the equation:

360 = 60t

Now, we can solve for 't' by dividing both sides of the equation by 60:

t = 360 / 60

Calculating the value:

t = 6

Therefore, it will take 6 hours for the two ships to be 360 km apart.
