Answer:
Jen is walking faster with a speed of 2.4 miles per hour compared to Kamlee's speed of 1.67 miles per hour.
Explanation:
To calculate their speeds in miles per hour, we need to convert the given distances and time intervals into the same units. Let's start by converting the time intervals to hours.
Jen:
- Distance walked: 4/5 mile
- Time taken: 20 minutes
To convert 20 minutes to hours, we divide by 60 since there are 60 minutes in an hour:
20 minutes ÷ 60 = 1/3 hour
So, Jen walked 4/5 mile in 1/3 hour.
Kamlee:
- Distance walked: 5/6 mile
- Time taken: 25 minutes
Again, let's convert 25 minutes to hours:
25 minutes ÷ 60 = 5/12 hour
Kamlee walked 5/6 mile in 5/12 hour.
Now, we can calculate their speeds:
Jen's speed: Distance ÷ Time = (4/5) ÷ (1/3) = (4/5) × (3/1) = 12/5 = 2.4 miles per hour
Kamlee's speed: Distance ÷ Time = (5/6) ÷ (5/12) = (5/6) × (12/5) = 10/6 = 1.67 miles per hour (rounded to two decimal places)
Have a nice day!
