A motor ship and a boat sailed from one pier simultaneously in opposite directions. After 2 hours of travel, the distance between them was 120 km. With what average speed did the motor ship sail if its speed was 2 times less than the speed of the boat?

1. Let’s find how many kilometers in 1 hour the boat and the motor ship passed together, if it is known that they covered 120 kilometers in 2 hours.
120/2 = 60 kilometers.
2. Let’s calculate the speed of the ship per hour, if it is said that its speed was 2 times less than the speed of the boat.
60/3 = 20 kilometers.
Answer: The average speed of the ship was 20 kilometers per hour.
