Solution by Steps
step 1
To find the cost per kilometer, we divide the total cost by the total distance. The total cost is 32andthetotaldistanceis32 and the total distance is 14 \frac{2}{9} \mathrm{~km}$
step 2
Convert the mixed number to an improper fraction: 1429=1269+29=128914 \frac{2}{9} = \frac{126}{9} + \frac{2}{9} = \frac{128}{9}
step 3
Now divide the total cost by the distance in kilometers: 321289\frac{32}{\frac{128}{9}}
step 4
Simplify the division by multiplying by the reciprocal of the denominator: 32×912832 \times \frac{9}{128}
step 5
Calculate the result: 32×9128=28812832 \times \frac{9}{128} = \frac{288}{128}
step 6
Simplify the fraction: 288128=94\frac{288}{128} = \frac{9}{4}
step 7
Convert the improper fraction to a mixed number: 94=214\frac{9}{4} = 2 \frac{1}{4}
Answer
2142 \frac{1}{4} or 2.252.25 per kilometer
