#### 81. How Far Will a Spacecraft Travel in 18 Hours If It Moves at 12,000 km in 4 Hours? Space exploration continues to captivate minds around the world, and one of the most fundamental calculations in space missions is determining how far a spacecraft travels based on speed and time. In this article, we explore a clear and practical example: if a spacecraft travels 12,000 kilometers in 4 hours, how far will it travel in 18 hours—assuming consistent speed? ### Understanding the Speed First, let’s calculate the spacecraft’s speed. Speed is the distance traveled divided by time taken. Using the given data:
