Answer:
75 mph
Step-by-step explanation:
In this kind of problem, "per" means "divided by". To find miles per hour, compute <em>miles divided by hours</em>:
(60 mi)/(4/5 h) = (60×5/4) mi/h = 75 mi/h
Nellie is going 75 miles per hour.
We know that
<span>the Consumer Price Index
(CPI) is equals to
</span>CPI=100*[cost of the pizza today/cost of the pizza <span>in the base year]
[</span>cost of the pizza in the base year]=100*[cost of the pizza today/CPI]
cost of the pizza today=$12
<span>CPI=200
so
</span>[cost of the pizza in the base year]=100*[12/200]-----> $6
<span>
the answer is
</span>The cost of the pizza in the base year is $6<span>
