Answer:
<em>Option C. Luigi runs 150 laps in 10 hours
. </em>
Step-by-step explanation:
<u>Unit Rate</u>
We need to match for an option having a unit rate of 15 laps per hour.
To find the required rate, we divide the number of laps by the number of hours.
A. Luigi runs 44 laps in 4 hour
. This gives a unit ratio of 44/4 = 11 laps/hour. This is not the correct option
B. Luigi runs 2 laps in 30 hours. This gives a unit ratio of 2/30 =0.07 laps/hour. This is not the correct option
C. Luigi runs 150 laps in 10 hours
. This gives a unit ratio of 150/10 = 15 laps/hour. This is the correct option
D. Luigi runs 60 laps in 5 hours. This gives a unit ratio of 60/5 = 12 laps/hour. This is not the correct option
Option C. Luigi runs 150 laps in 10 hours
.
Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class (
)
Cross multiply
2 * 40 = 5 * A
80 = 5A
Isolate A by dividing 5 to both sides
80/5 = 5A/5
16 = A
If 40 people in the class got B's then 16 people got A's

Answer:
The answer is C.
Step-by-step explanation:
The formula to find equation is y - y1 = m(x - x1).
Let (x1,y1) be (6,2) and m is -5/7.
So the equation is,
y - 2 = -5/7(x - 6)
