Answer: 7.5 mph
Explanation:
To calculate your speed in miles per hour (mph), you can use the following formula:
Speed (mph) = Distance (miles) / Time (hours)
In this case, you ran 1.5 miles in 12 minutes. To convert the time from minutes to hours, you divide by 60 (since there are 60 minutes in an hour):
Time (hours) = 12 minutes / 60 = 0.2 hours
Now, plug the values into the formula:
Speed (mph) = 1.5 miles / 0.2 hours = 7.5 mph
So, your speed was 7.5 miles per hour when you ran 1.5 miles in 12 minutes.
