after filling a gas tank the odometer read 27,892.5. after the next filling it resd 28,176.0. it took 16.5 gal to fill the tank. how many miles per gallon did the driver get?

Answer 1

Given data:

The initial reading of odometer is i=27,892.5 miles.

The final reading is f=28,176.0

The gallons is g=16.5

The change in reading per gallon is,

$r=\frac{f-i}{g}$

Substitute the given values in the above expression.

$\begin{gathered} r=\frac{28,176-27,892.5}{16.5} \\ =17.1818\text{ miles/gallon} \end{gathered}$

Thus, the miles per gallon driver got is 17.1818.
