Mrs. Walters: 14.4 miles per gallon
Mr. Walters: 15 miles per gallon
Mr. Walters is getting the better mileage per gallon.
Ft. Lauderdale is a city that stretches several miles, and Haiti
is a whole country, that's many miles wide and many miles high.
In order to nail down a reliable answer, you'd really need to specify
one point in Ft. Lauderdale and one point in Haiti.
If you start at the northwest end of Runway-13 at Ft. Lauderdale
Executive Airport, and take the shortest possible route to the east
end of Runway-28 at the Aeroport International de Port au Prince
at Haiti's capital city, you'd have to travel 727.57 miles.
But if you start in Ft. Lauderdale at the intersection of Griffin Rd
and Ravenswood Rd, and take the shortest possible route to the
Dispensaire de Bord-de-Mer hospital on Haiti's north coast, you'd
only have to travel 613.63 miles.
You really need to say WHERE in Ft. Lauderdale and WHERE in Haiti.
B. is the answer if you look closely
