Question

The advertised mpg for new cars is based on a speed of 55 mph. As speed increases above 55 mph, the efficiency reduces dramatically (MPG for speed, 2014). 3% less efficient at 60 mph 17% less efficient at 70 mph. Make sure that you fill in each answer area before checking "How Did I Do?". Compare the efficiency of a Toyota Camry (33 mpg highway) versus a Toyota Prius (48 mpg highway) at speeds of 55 mph, 60 mph, and 70 mph.

Answer 1

Answer:

See the explanation.

Step-by-step explanation:

The efficiency of Toyota Camry is 33 mpg highway.

At speeds of 55 mph, Toyota Camry's efficiency is 33 mpg highway.

At 60 mph, the efficiency of Toyota Camry will reduce 3%, that is (100 - 3) = 97% of 33 = $\frac{97\times33}{100} = 32.01$ mpg highway.

At 70 mph, the efficiency of Toyota Camry will reduce 17%, that is (100 - 17) = 83% of 33 = $\frac{33\times83}{100} = 27.39$ mpg highway.

At speeds of 55 mph, the efficiency of Toyota Prius is 48 mpg highway.

At 60 mph, the efficiency of Toyota Prius will reduce 3%, that is (100 - 3) = 97% of 48 = $\frac{97\times48}{100} = 46.56$ mpg highway.

At 70 mph, the efficiency of Toyota Prius will reduce 17%, that is (100 - 17) = 83% of 48 = $\frac{83\times48}{100} = 39.84$ mpg highway.
