Step-by-step explanation:
1 mile = 1.6 km
So, every 7 minutes, 1.6 km is ran.
Divide 1.6 by 2 to figure out how much more she is running.
1.6 / 2 = 0.8
Divide the known pace by the extra distance to figure out the time
7 min / 0.8 km = 8.75 min

Answer:
2019.
Step-by-step explanation:
We have been given that for the years from 2002 and projected to 2024, the national health care expenditures H, in billions of dollars, can be modeled by
where t is the number of years past 2000.
To find the year in which national health care expenditures expected to reach $4.0 trillion (that is, $4,000 billion), we will substitute
in our given formula and solve for t as:




Take natural log of both sides:





So in the 18.5 years after 2000 the expenditure will reach 4 trillion.

Therefore, in year 2019 national health care expenditures are expected to reach $4.0 trillion.
