Kathleen has been tracking how fast she walks over the last moth and determined that she walks 1 1/4 of an hour. Lynn has been tracking how fast she walks over the past few weeks and determined that it takes her 19 min and 12 seconds to walk one mile. Write Kathleen's and Lynn's walking rate in the same format.
Part B: Give a logical argument on why that format was chosen over the other three.
I don't know the answer
To write Kathleen's walking rate in the same format as Lynn's, we need to convert Kathleen's time from 1 1/4 hours to minutes and seconds.
1 1/4 hour can be written as 1 hour + 1/4 hour.
1 hour is equal to 60 minutes, so we write it as 60 minutes.
1/4 hour is equal to 1/4 * 60 = 15 minutes.
So, Kathleen's time of 1 1/4 hour is equal to 60 minutes + 15 minutes = 75 minutes.
Now, let's convert Lynn's time into minutes and seconds.
19 minutes and 12 seconds can be written as 19 minutes + 12 seconds.
So, Lynn's time is 19 minutes and 12 seconds.
Therefore, Kathleen's walking rate is 75 minutes, and Lynn's walking rate is 19 minutes and 12 seconds.
.... she walks 1 1/4 of an hour.
Huh?
