Question
Matthias’ car consumes an average of 11 litres of fuel per 100 kilometres for citydriving, and 8 litres per 100 kilometres for country driving.If Matthias takes a trip where he travels 62 kilometres in the city and 230kilometres in the country, what is his expected fuel consumption?A 28.66 LB 25.22 LC 32.16 LD 27.74 L
Solution
To solve this problem, we need to calculate the fuel consumption for both city and country driving separately and then add them together.
-
City driving: Matthias' car consumes 11 litres of fuel per 100 kilometres. So, for 62 kilometres, the fuel consumption would be (11/100)*62 = 6.82 litres.
-
Country driving: The car consumes 8 litres of fuel per 100 kilometres. So, for 230 kilometres, the fuel consumption would be (8/100)*230 = 18.4 litres.
-
Now, add the fuel consumption for city and country driving together: 6.82 litres + 18.4 litres = 25.22 litres.
So, the expected fuel consumption for Matthias' trip is 25.22 litres. The correct answer is B 25.22 L.

Watzandi drives an average of 537 kilometers per month in a vehicle that only gets 15 kilometers per litre overall. With the cost of petrol at $666.09 per litre, approximately how much would she save each year on petrol if she drove a car that got 33 kilometers per litre instead?(Round your final answer to the nearest whole dollar, and don't include the dollar sign in your answer.)
Use the following regression equation regarding car mileage to answer the question. Highway = 0.892+1.337 (City) Note that City is the estimated miles per gallon (mpg) a car gets while driving on city streets, and Highway is the estimated miles per gallon (mpg) a car gets while driving on highways. What is the expected miles per gallon in the Highway if a car in the City gets 23 miles per gallon? Round to one decimal place.
