Final answer:
To calculate their speeds in miles per hour, we need to determine the distance each person walked and the time it took for them to walk that distance. We can compare their speeds to identify who is walking faster.
Step-by-step explanation:
To calculate their speeds in miles per hour, we need to determine the distance each person walked and the time it took for them to walk that distance. Let's assume that Jen walked a distance of d1 in 20 minutes, and Kamlee walked a distance of d2 in 25 minutes.
Using the formula speed = distance / time, we can calculate the speeds as follows:
Jen's speed = d1 / 20 minutes.
Kamlee's speed = d2 / 25 minutes.
To identify who is walking faster, we can compare their speeds. If Jen's speed is greater, then she is walking faster. If Kamlee's speed is greater, then she is walking faster.
