I believe it's 1 mile.

Answer 2

Melissa walked at a rate of 1.0 miles per hour.

Explanation:

As given

Melissa walked at a rate of 88 feet per minute .

As

`1\ minutes = (1)/(60)\ hour`

`1\ feet = (1)/(5280)\ hour`

Now convert 88 feet per minutes into miles per hour.

`(88\ feet)/(minutes)= (88* (1)/(5280))/((1)/(60))\ miles\ per\ hour`

`(88\ feet)/(minutes)= ((88)/(5280))/((1)/(60))\ miles\ per\ hour`

`(88\ feet)/(minutes)= (0.017)/(0.017)\ (Approx)\ miles\ per\ hour`

`(88\ feet)/(minutes)= 1.0\ miles\ per\ hour`

Therefore the Melissa walked at a rate of 1.0 miles per hour.
