Solution Steps

Step 1: Understanding the Concept of Speed

Speed is defined as the distance traveled per unit of time. Therefore, acceptable units of speed must have a distance unit divided by a time unit.

Step 2: Evaluating Each Option
  1. Meters per mile: This is not a valid unit of speed because it represents a distance per distance.
  2. Inches per decade: This is a valid unit of speed because it represents a distance (inches) per time (decade).
  3. Centimeters per day: This is a valid unit of speed because it represents a distance (centimeters) per time (day).
  4. Meters per second per second: This is not a valid unit of speed because it represents acceleration, not speed.
  5. Miles per hour: This is a valid unit of speed because it represents a distance (miles) per time (hour).
  6. Days per year: This is not a valid unit of speed because it represents a time per time.

Final Answer

\[ \boxed{\text{Inches per decade, Centimeters per day, Miles per hour}} \]
