on the way to the Open Air Museum Jaz and Kim stop to buy petrol.The petrol costs $3.15 for one USE gallon.
Kim wants to compare the cost of petrol in America with the cost of petrol in England.
Kim uses this information
- 1 US gallon=3.875 litres
- 1 litre of petrol in England cost £1.37
-£1=$1.60
Kim says that the price f petrol in England is more than 2 times the price of petrol in America.
Is Kim is correct?
Show why you think this.
$3.15/3.875 = $.81
Compare to $1.60
Not "more than 2 times the price."
To determine if Kim is correct in her statement that the price of petrol in England is more than 2 times the price of petrol in America, we need to compare the prices in both countries.
First, let's convert the cost of petrol in America to liters using the conversion given:
1 US gallon = 3.875 liters
So the cost of petrol in America per liter can be calculated as:
$3.15 / (1 US gallon * 3.875 liters) = $0.2042 per liter
Next, let's convert the cost of petrol in England from pounds to dollars using the exchange rate given:
£1 = $1.60
Now, we need to convert the cost of petrol in England from liters to dollars. For that, we'll multiply the cost in pounds by the exchange rate and divide it by the cost of 1 liter of petrol in England:
Cost of petrol in England per liter in dollars:
(£1.37 * $1.60) / 1 liter = $2.192 per liter
Comparing the two prices, we find that:
$2.192 (cost per liter in England) > $0.2042 (cost per liter in America)
Therefore, Kim is correct in stating that the price of petrol in England is more than 2 times the price of petrol in America.
