A woman drives an SUV that gets 12 mi/gal (mph). Her husband drives a hybrid that gets 55 mph. Every week, they travel the same number of miles. They want to improve their combined not. They have two options on how they can improve it. Option1:They can tune the SUV and increase its mileage by 1 mph and keep the hybrid as it is. Option 2: they can buy a new hybrid that gets 80 mph and keep the SUV as it is . Which option will give them a better combined mph?

Option 2 gives a better combined mileage.

Step-by-step explanation:

Data provided in the question:

Mileage of SUV = 12 mi/gal

Mileage of hybrid = 55 mph or 55 mi/gal

After tuning the SUV, new mileage = 12 + 1 = 13 mi/gal

Now,

For Option 1:

Average mileage of SUV and the Hybrid =

= 34 mi/gal

For Option 2:

Mileage of new car = 80 mph or 80 mi/gal

Average mileage =

= 46 mi/gal

Hence,

Option 2 gives a better combined mileage.
