Answer:
Melissa walked at a rate of 1.0 miles per hour.
Step-by-step explanation:
As given
Melissa walked at a rate of 88 feet per minute .
As
\(1\ minutes = \frac{1}{60}\ hour\)
\(1\ feet = \frac{1}{5280}\ hour\)
Now convert 88 feet per minutes into miles per hour.
\(\frac{88\ feet}{minutes}= \frac{88\times \frac{1}{5280}}{\frac{1}{60}}\ miles\ per\ hour\)
\(\frac{88\ feet}{minutes}= \frac{\frac{88}{5280}}{\frac{1}{60}}\ miles\ per\ hour\)
\(\frac{88\ feet}{minutes}= \frac{0.017}{0.017}\ (Approx)\ miles\ per\ hour\)
\(\frac{88\ feet}{minutes}= 1.0\ miles\ per\ hour\)
Therefore the Melissa walked at a rate of 1.0 miles per hour.
