Question

your car gets 32.4 miles/gallons and your tank holds 14.25 gallons of gas.

How far can you go, in miles. on one tank of gas?

if gas cost $2.11 per gallon, how much will one tank of gas cost?

How much will it cost in euros to drive 1200 km?Gas cost E1.20 per liter and there are $1.09 in 1.00E.

Answer 1

€€a) Your full tank of gas will let you travel
  (32.4 mi/gal)*(14.25 gal) = 461.7 mi

b)The cost of that tank of gas is
  (14.25 gal)*($2.11/gal) = $30.07

c) The cost in Euros can be figured from
$\dfrac{1\,gal}{32.4\,mi}\cdot \dfrac{\ 2.11}{1\,gal}\cdot \dfrac{1.00\,Euros}{\ 1.09}\cdot \dfrac{1\,mi}{1.609344\,km}\cdot(1200\,km)\\\\=\dfrac{2.11\cdot1200}{32.4\cdot1.09\cdot1.609344}\,Euros\\\\=44.55\,Euros$

The cost is €44.55 for 1200 km.
