Answer:
the gas mileage would be 21.12 mi/gal
Explanation:
The computation of the gas mileage is shown below:
Given that
Driving into a 20-mph
Gas mileage by approx 12%
No wind at 24mi/gal
based on the above information
The deduction would be
= 12% × 24
= 2.88 mi/gal
Now the actual mileage in 20-mph would be
= 24 - 2.88
= 21.12 mi/gal
hence, the gas mileage would be 21.12 mi/gal
