# Two ships are moving towards each other. Now there are 185.5 km between them. The first motor ship

**Two ships are moving towards each other. Now there are 185.5 km between them. The first motor ship has its own speed of 24.5 km / h and moves with the current, and the second motor ship has its own speed of 28.5 km / h and moves against the current. In how many hours will they meet if the current speed is 2.5 km / h?**

To solve this problem, you need to write an equation.

In order to understand at what speed each of the ships was moving, you need to take into account the speed of the water flow. If the ship is sailing with the current, then its speed is added up with the speed of the current, if against it, it is subtracted.

24.5 + 2.5 = 27 km / h – the speed of the first motor ship that floats with the stream,

28.5 – 2.5 = 26 km / h – the speed of the second motor ship, which is sailing against the current.

x – the time that the ships were on the way.

Each ship was on the way for the same time and together they sailed 185.5 km, we make the equation:

27x + 26x = 185.5

53x = 185.5

x = 3.5

Answer: the ships will meet in 3.5 hours (3 hours 30 minutes)
