To convert 168 miles per week to miles per hour, you need to determine how many hours are in a week. There are 24 hours in a day and 7 days in a week:
\[ 24 \text{ hours/day} \times 7 \text{ days/week} = 168 \text{ hours/week} \]
Next, divide the total miles by the total hours to find the equivalent rate in miles per hour:
\[ \text{Rate (miles/hour)} = \frac{168 \text{ miles}}{168 \text{ hours}} = 1 \text{ mile/hour} \]
Therefore, 168 miles per week is equivalent to 1 mile per hour.
