This question illustrates the importance of ALWAYS checking the answer choices BEFORE getting bogged down with time-consuming calculations.
Since the answer choices are VERY spread apart, we can be quite aggressive in our rounding and estimation.
In 1979 approximately 1/3 of the 37.3 million airline passengers traveling to or from the United States used Kennedy Airport.
Let's say that "In 1979 approximately 1/3 of the 36 million airline passengers traveling to or from the United States used Kennedy Airport. "
1/3 of 36 = 12
So, 12 million passengers used Kennedy Airport
The number of such passengers that used Miami Airport was 1/2 the number that used Kennedy Airport
12 million passengers used Kennedy Airport
1/2 of 12 million = 6 million
So, 6 million passengers used Miami Airport
The number of such passengers that used Miami Airport was 4 times the number that used Logan Airport
In other words, the number of such passengers that used Logan Airport was 1/4 the number that used Miami Airport
1/4 of 6 million = 1.5 million
So, 1.5 million passengers used Logan Airport
Check the answer choices . . . only answer choice E is close to 1.5
Answer: E
