A boat and a motor ship sailed from two piers at the same time towards each other. The speed of the ship is 18 km / h, and the speed of the boat is 16 km / h. What is the distance between them if they sailed for 4 hours?

1. It is known that the motor ship and the boat met after 4 hours. This means that the distance between the piers is equal to the sum of the distances that the boat and the motor ship sailed.

2. Let’s find the distance that the motor ship sailed:

18 * 4 = 72 km.

3. Find the distance that the boat has sailed:

16 * 4 = 64 km.

4. The distance between the piers is equal to:

72 + 64 = 136 km.

Answer: The distance between the marinas is 136 km.
