A tourist purchases a car in england and ships it home to the united states. the car sticker advertised that the car's fuel cons
Valentin [98]

<u>Solution-</u>

Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)

1 UK gallon = 4.5459631 lit

1 US gallon = 3.7853060 lit

\therefore \frac{1 \ UK \ gallon}{1 \ US \ gallon} = \frac{4.5459631}{3.7853060} = 1.2009499

\Rightarrow 1 \ UK \ gallon = 1.2009499 \ US \ gallon

As the fuel consumption rate = 40 miles per gallon

⇒ You need 1 UK gallon of fuel to go 40 miles

⇒ You need 1.2009499 US gallon of fuel to go 40 miles

Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel

⇒ To go 1 mile you will need  \frac{1.2009499}{40} = 0.0300237

⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel

∴ 22.1574906 gallon of fuel is actually required.

∴ But, what she thinks will require is \frac{738}{40} = 18.45 gallons (As she calculated using UK gallons)

The cost for taking a taxi is $1.80 plus $0.10 per eighth of a mile. What is the cost of a ride that is 4.5 miles long?
Sergio039 [100]

Answer:

$1.80 + (8x$0.10)*4.5 = $5.40

Step-by-step explanation:

$1.80 base cost

$0.10 for an 8th of a mile, thus multiply by 8 = $0.80 per mile

So, $1.80 + (4.5 * $0.8) = $5.40
