The motor ship travels 48 km along the river in 3 hours, and the raft takes 24 hours.

The motor ship travels 48 km along the river in 3 hours, and the raft takes 24 hours. What is the speed of the motor ship when moving along the lake?

The solution of the problem:
1. To solve the problem, let us find at what speed per hour the motor ship went along the river, if it is known that in 3 hours it covered a distance of 48 kilometers.
48/3 = 16 kilometers.
2. Let’s calculate the speed of the river, if we know that the raft along the river swam 48 kilometers in 24 hours.
48/24 = 2 kilometers per hour.
3. Let’s find out what is the speed of the ship when moving along the lake.
16 – 2 = 14 kilometers.
Answer: The speed of the motor ship on the lake will be fourteen kilometers per hour.
