SOLUTION: 3% less efficient at 60 mph 17% less efficient at 70 mph. Compare the efficiency of a Toyota Camry (33 mpg highway) versus a Toyota Prius (48 mpg highway) at speeds of 55 mph,

Question 1128021: 3% less efficient at 60 mph
17% less efficient at 70 mph.
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.
I got this far: Camry at 60mph is 32.0 mpg, and 27.4 mpg at 70mph.
The Prius gets 46.6mpg at 60 mph, and 39.8mpg at 70mph.
But now I'm stuck:
If gasoline costs $3.52 per gallon, how much money would you save by going 60 mph versus 70 mph on the trip of 1,500 miles in the Camry? Prius?
How much longer, to the nearest minute, would it take to travel 360 miles at 60 mph versus 70 mph?
