Match the unit with what it measures.
mi/d2
yd
y
in/d
Speed
Displacement
Acceleration
Time
To match the units with what they measure, we need to analyze the given units and identify the corresponding measurement.
1. mi/d2: This unit represents acceleration. The unit "mi" stands for miles, and "d2" stands for square units of time, which indicates the rate of change of velocity over time. Therefore, the correct match is "Acceleration."
2. yd: This unit represents displacement. "yd" stands for yards, and it measures the change in position or distance between two points. Therefore, the correct match is "Displacement."
3. y: This unit represents time. "y" usually stands for years, which is a measurement of the duration or passage of time. Therefore, the correct match is "Time."
4. in/d: This unit represents speed. "in" stands for inches, and "d" stands for units of time. Speed measures how quickly an object moves or the rate of change of distance over time. Therefore, the correct match is "Speed."
