Final answer:
To find the unit rate in miles per hour, divide the distance by the time. In this case, Jon travels at a unit rate of 2 miles per hour.
Step-by-step explanation:
To find the unit rate in miles per hour, we need to convert the given information into the same units. Jon travels 1/2 mile in 1/4 hour, so we can simplify the fraction to 2/4, which is equal to 1/2. This means Jon travels 1/2 mile every 1/4 hour. To find the unit rate, we divide the distance (1/2 mile) by the time (1/4 hour).
1/2 mile ÷ 1/4 hour = 2 miles per hour
Therefore, the unit rate at which Jon travels is 2 miles per hour.
