Final answer:
To calculate the average speed, the distance of 1.5 miles is divided by the time of 25 minutes, converted to hours (0.4167 hours), resulting in an average speed of approximately 3.6 miles per hour.
Step-by-step explanation:
To find the average speed in miles per hour, you need to divide the total distance by the time taken to travel that distance. However, it's important to convert all your units to the same system. Since speed is needed in miles per hour and the time given is in minutes, you should first convert the 25 minutes of rollerblading into hours.
To do this, divide the 25 minutes by 60, since there are 60 minutes in one hour:
- 25 minutes ÷ 60 minutes per hour = 0.4167 hours (approximately).
Next, divide the distance traveled (1.5 miles) by the time spent traveling in hours to find the average speed:
- 1.5 miles ÷ 0.4167 hours = 3.6 miles per hour (approximately).
Therefore, the average speed of rollerblading is 3.6 miles per hour.
