Final answer:
Jessica's walking rate is calculated by dividing the distance she covered, which is 0.5 miles, by the time it took in hours, which is 1/6 hour. Her walking rate is 3 miles per hour.
Step-by-step explanation:
To calculate Jessica's rate in miles per hour, we first determine the distance she covered and the time it took for her walk from the 0.6-mile point to the 0.1-mile point.
Distance covered by Jessica = 0.6 miles - 0.1 miles = 0.5 miles
Time taken to cover that distance = 12 minutes - 2 minutes = 10 minutes
To find her speed in miles per hour, we need to convert the time taken from minutes to hours:
Time in hours = 10 minutes ÷ 60 minutes/hour = 1/6 hours
Now, we calculate the rate:
Rate in miles per hour = Distance ÷ Time
Rate in miles per hour = 0.5 miles ÷ (1/6 hours)
Rate in miles per hour = 3 miles per hour
