Answer:
16 miles per gallon.
Step-by-step explanation:
On Monday Marci filled her car's tank and the odometer read 32,461.3 miles.
On Friday she filled the tank again and the odometer read 32,659.7 miles
It took 12.4 gallons to fill the tank
The distance covered by the car from Monday to Friday = 32,659.7 miles - 32,461.3 miles = 198.4 miles
The car depleted 12.4 gallons of fuel after travelling for the 198.4 miles
So one gallon would take Marci's car: [tex]\frac{1 times 198.4}{12.4}[/tex] miles
= 16 miles.
Marci's car gets a total of 16 miles per gallon rate so option (A) will be correct.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
The ratio is very useful to find out the results while in decimals it becomes complicated to calculate them.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given,
Marci cars travel = 32659.7 - 32461.3 = 198.4 miles.
The amount of fuel consumption = 12.4 gallons.
So,
The rate of consumption in miles per gallon will be
198.4/12.4 = 16 miles/gallon
Hence the rate of consumption of fuel per gallon will be 16 miles per gallon.
