Given the statement:
A model car is 2.5 inches long. The real car is 13 feet long.
Determine the unit rate that describes the relationship of the real car to the model car.
Solution:
In order to determine the unit rate, we must first change 13 feet to inches in order to have the same unit of measurement.
1 feet = 12 inches
13 feet = 156 inches
Now we must equate the relationship in one single solution.
2.5 inches = 156 inches
or as a ratio of proportionality,
2.5:156
Final answer:
2.5 inches = 156 inches
2.5:156
