Question

A ________ compares a quantity to one unit of another quantity.

• A. proportion
• B. equivalent ratio
• C. ratio
• D. unit rate

Answer 1

The correct option is D unit rate

A unit rate compares a quantity to one unit of another quantity.
For example, if a car covers $50$ miles in $2$ hours, we can say that the rate at which it covers the distance is $\frac{\text{50 miles}}{2\text{hours}}=25\text{mi per h}$
