Question

Два порохода вышли из порта.Один из них следует на север ,другой на запад. Скорости их равны соответственно 10км/ч и 24км/ч.Какое расстояние (в километрах) будет между ними через 4 часа?

Answer 1

24-10=14 (км/ч)-скорость удаления
14×4=56 (км)- будет между ними через 4 часа

Answer 2

Calculation of Distance Between Two Ships

To calculate the distance between two ships, one heading north and the other heading west, we can use the formula for calculating the distance between two points in a plane. The formula is:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, we can consider the starting point of both ships as the origin (0,0) on a coordinate plane. The ship heading north will have a y-coordinate of 10 km/h * 4 hours = 40 km, and the ship heading west will have an x-coordinate of 24 km/h * 4 hours = 96 km.

Using the formula, we can calculate the distance between the two ships:

Distance = √((96 - 0)^2 + (40 - 0)^2)

Distance = √(96^2 + 40^2)

Distance = √(9216 + 1600)

Distance = √10816

Distance ≈ 104 km

Therefore, the distance between the two ships after 4 hours will be approximately 104 kilometers.
