Answer:
0.5 miles/ 10 minutes* (60 minutes/ 1 hour)= 3 miles/hour.
0.25 miles/ 6 minutes* (60 minutes/ 1 hour)= 2.5 miles/hour.
The unit rate of Ron is 3 miles/hour.
The unit rate of Steve is 2.5 miles/hour.
Therefore, Ron walks faster~
Step-by-step explanation:
Answer: 5/6 inch/minute
Whenever you are working with a question of rate where two different quantities are being compared, the required units will indicate which quantity is to be divided by which.
In this case you want to know inches per minute.Therefore:
5

6z - 3z - 7 = -2 + 3
Combine like terms
3z-7 = 1
Add 7 to each side
3z-7+7 = 1+7
3z=8
Divide each side by 3
3z/3 = 8/3
z = 8/3
There is one solution

How I got that answer:
The data set for Marcus is
2, 3, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10
The five number summary is
So the interquartile range (IQR) is
IQR = Q3 - Q1
IQR = 8 - 6
IQR = 2
