Answer 1

Answer:

Correction! Unit Rate. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Some common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc.

Answer 2

I would say the correct term to fill in the blank would be unit. A unit rate represents how many of a certain unit corresponds to another one unit. For instance, 200 miles per 1 hour, 5 kg/s, 16 m^3/min. Hope this answers the question.<span />
