Answer:
The fastest runner is Katie
Step-by-step explanation:
In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.
Katie
14 feet/1 second = 14 ft per second
Zach
576 feet/46 seconds = 12.52 ft per second
Tony
1 mile/533 seconds = 5280 feet/533 seconds = 9.91 ft per second
Will
827 feet/1 minute = 827 feet/60 seconds = 13.78 ft per second.
So we know that the fastest is Katie.
Answer: 13n + 20
Step-by-step explanation:
The cost of each book is $13. That means that if you end up buying "n" books, cost would be:
= Cost of each book * number of books
= 13 * n
= 13n
You would also get charged a flat rate for shipping of $20 which would be added to the above cost to bring a total of:
= 13n + 20
Answer:
Option D doesn't make any sense.
Step-by-step explanation:

hours = 8 + 0.5*(18 -age)
hours = 8 + 0.5*(18 -19)
hours = 8 + 0.5*(-1)
hours = 7.5
