Question

Find one of these is an example of a unit rate.

  1. Miles per hour
  2. Total of a grocery bill
  3. 2 Feet every five seconds
  4. 4 Boys for every 6 girls

hintHint:

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.
