Answer:
<h2>See the explanation.</h2>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 = mpg highway.
At 70 mph, the efficiency of Toyota Camry will reduce 17%, that is (100 - 17) = 83% of 33 = 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 = mpg highway.
At 70 mph, the efficiency of Toyota Prius will reduce 17%, that is (100 - 17) = 83% of 48 = mpg highway.
