Question

Emanuel was charged $32 for a 14 2/9 km taxi ride. What was the cost per kilometer?

Answer 1

Answer:

$2.25 per kilometer

Step-by-step explanation:

Here we are asked for the unit rate, dollar per kilometer, that is $\ /km$.

If Emanuel was charged $32 we need to divided that amount by the kilometers traveled, so:

$x=\frac{\ 32}{(14+\frac{2}{9})km}\\x=\frac{\ 32}{\frac{128}{9}km}\\\\x= \frac{\ 288}{128km}\\\\x=2.25\frac{\ }{km}$

So the cost per kilometer traveled is $2.25.

Answer 2

32 / (14 2/9) = 
32 / (128/9) =
32 * 9 / 128 =
288 / 128 =
$ 2.25 per km
