Answer:
Grady ran on Monday, Wednesday, Friday, and Saturday this week. To determine on which day he ran the fastest, we need to compare the time it took for each run.
According to the provided data, Grady took 24 minutes to run on Monday, 32 minutes on Wednesday, 42 minutes on Friday, and 58 minutes on Saturday. From these times, we can conclude that Grady ran the fastest on Monday since it took him the least amount of time.
It is important to note that the distance Grady traveled is not relevant in determining the fastest run. However, for completeness, we have the distance data as well. Grady ran a total distance of 36 miles throughout the week. On Monday, he ran 3 miles, on Wednesday he ran 6 miles, on Friday he ran 7 miles, and on Saturday he ran 9 miles.
In summary, Grady ran the fastest on Monday based on the time it took him to complete his run.
