Question

While in europe, if you drive 113 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 41.0 mi/gal ? assume that 1euro=1.26dollars?

Answer 1

113 x 7 = 791 km per week
791 km ~ 491.5 miles

491.5/41 = 12 gallons used

1 galloon ~ 3.8 liters

45.6 liters used

45.6 x 1.10 euros = 50.16 Euros used or $63.20 dollars used.

Answer 2

`\$63.04`

Explanation:

Distance traveled in
`1` day =
`113 km`

Distance traveled in
`1` week =
`113*7 = 791 km`

Mileage of car =
`41.0 mi/gal = (41*1.60)/(3.78) = 17.35 km/liter`

Total gas consumed =
`(791)/(17.35) = 45.49liter`

Cost of
`1liter` gas =
`1.10 euros = 1.10*1.26 = \$1.386`

Money spent on gas in a week =
`45.49*1.386 = \$63.04`
