#### Answer

The mean can help the Airlines calculate their total flight times.

#### Work Step by Step

The mean can be counted by summing all the data and dividing it by the number of data: for white drivers: $\frac{30+19+12+...+23}{48}=20.98$. The median is the average of the 1 or 2 (here 2) middle data:(18+19)/2=18.5. The mean can help the Airlines calculate their total flight times.
