Question

If a car travels 360 miles on 21 gallons of gas how many miles per gallon does it average (to the nearest tenth)

Answer 1

Solution:

Concept:

The formula that will be used to calculate the average miles per gallon is given below as

$\text{Average(miles per gallon)=}\frac{Number\text{ of miles}}{Nu\text{mber of gallons}}$

The number of miles traveled by car is

$=360\text{ miles}$

The number of gallons consumed is

$=21\text{ gallons}$

By applying the formula and substituting the values, we will have

$\begin{gathered} \text{Average(miles per gallon)=}\frac{Number\text{ of miles}}{Nu\text{mber of gallons}} \\ \text{Average(miles per gallon)}=\frac{360\text{ miles}}{21\text{ gallons}} \\ \text{Average(miles per gallon)}=17.14\text{ miles per gallon} \\ to\text{ the nearest tenth, we will have} \\ \text{Average(miles per gallon)}=17.1\text{ miles per gallon} \end{gathered}$

Hence,

The final answer = 17.1 miles per gallon
