(1/5) / 4.5 = 2 / m....1/5 mile to 4.5 minutes = 2 miles to m minutes
cross multiply
(1/5)(m) = (2)(4.5)
1/5m = 9
m = 9 * 5/1
m = 45 minutes <===
Answer:
The best estimate for the average rate of change is 
Step-by-step explanation:
we know that
the average rate of change using the graph is equal to
In this problem we have
Substitute
you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.
After converting to common denominator:
8/18, 7/18, 6/18, 5/18
so the next fraction is 4/18, but if you have to simplify it’s 2/9
