Final answer:
To find Alex's unit rate in miles per hour, we need to convert the time from hours to minutes and the distance from miles to hours. First, we'll convert the time: 1/4 hour = 15 minutes. Then, we'll convert the distance: 2/3 mile in 15 minutes = (2/3) * (60/15) = 8/3 miles per hour.
Step-by-step explanation:
To find Alex's unit rate in miles per hour, we need to convert the time from hours to minutes and the distance from miles to hours.
First, we'll convert the time:
1/4 hour = 15 minutes
Then, we'll convert the distance:
2/3 mile in 15 minutes = (2/3) * (60/15) = 8/3 miles per hour
Therefore, Alex's unit rate is 8/3 miles per hour.
