Question
Find one of these is an example of a unit rate.
- Miles per hour
- Total of a grocery bill
- 2 Feet every five seconds
- 4 Boys for every 6 girls
Hint:
A unit rate can be used to describe how many units of the first type of quantity corresponds to one unit of the second type of quantity.
The correct answer is: Miles per hour
Here, we have to select the correct option of unit rate.
We know that, R = D/T.
Miles per hour is an example of a unit rate because miles represent distance and hours represent time.
Hence, the correct option is (a).
All rate problems can be solved by using the formula, D = R(T), where, D is distance, R is rate and T is time.
