Sarah wants to buy the car that has a better mileage rating. Cars of Company A travel 20 miles per gallon, and cars of Company B travel 14 km per liter.
[1 mile = 1.6 km; 1 gallon = 3.79 liters]
Part A: Which company's car should Sarah buy? Justify your answer by comparing the mileages after converting to the same units. (5 points)
Part B: If 10 gallons of gas is filled in the car which gives better mileage and you went on a drive and checked on the gas used every 30 miles, describe appropriate scales on the xaxis and yaxis to graph the rate at which the car uses gas. (5 points)

Best ResponseYou've already chosen the best response.0Aim: to assess which has the better mileage rating. Given:Cars of Co. A travel 20 mile/gallon. Cars of Co.B travel 14km per litre. Given: 1 mile = 1.6km; 1 gallon = 3.79 litres. Solution: since we are asked about 'mileage', lets convert Co. B to miles. Now since 1 mile = 1.6 km dividing both sides by 1.6 we get: then 0.625 miles = 1 km therefore 14km = 0.625m x 14 = 8.75 miles

Best ResponseYou've already chosen the best response.0We now know that Co.A does 20 miles/gallon, and Co.B does 8.75miles/litre. burt we are given: 1 gallon = 3.79 litres. So, if Co. B used 1 gallon (i.e.3.79 litres), they would do 3.79 x 8.75 miles = 33.1625 miles. i.e Co.A Does 20 miles/gallon and Co.B does 33.1625 miles per gallon.

Best ResponseYou've already chosen the best response.0Firstly, we have already determined "the car which gives better mileage" (i.e. car from Co.B) We know it does 33.1625 miles per gallon. In part B, we are told it was filled with 10 gallons, therefore it can do 10 x 33.1625miles = 331.625 miles (shift the decimal point one place to the left to multiply by 10). so your x axis (which is miles) should go to about 340miles. And your y axis (no.of gallons) should at least be 10.
