help. please. 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. 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 x-axis and y-axis to graph the rate at which the car uses gas.
Part A convert company A to B measurements 20 x 1.6 and 3.79 liters Then you have A in km and liters, compare to which is more efficient Part B is pretty easy as well. Use mp/g rate of more efficient car, graph done as explained in question.
No problem. If you have any more questions just post them and I'll try my best.
