Correct answer

6 miles

  1. A 6 miles
  2. B 7 miles
  3. C 5 miles
  4. D 8 miles

Why this is the answer

Arrange in order: 4, 5, 6, 7, 8. The median (middle value) is 6 miles. Median means the middle value once the numbers are sorted — not the middle of the original list. Here the mean also happens to be 6 (30 ÷ 5), but on the test the two usually differ, so always sort first. With an even count of values, the median is the average of the two middle numbers.
