When dealing with different time zones, it is best to calculate the problem in one time zone then adjust it to the correct time
zone.
If it is 6:00 AM in Los Angeles when it is 9:00 AM in Pittsburgh, then Los Angeles is 3 hours behind Pittsburgh.
If a plane leaves Pittsburgh at 9:00 AM EST and arrives in LA at 11:00 AM PST (2:00 PM EST), then it took 5 hours to travel
from Pittsburgh to LA.
If a plane leaves LA at 10:00 AM and arrives in Pittsburgh 5 hours later, then it is 3:00 PM PST. Add 3 hours to get Pittsburgh
time, which is 6:00 PM EST.

Be very meticulous in your calculations and make sure that your final answer is the value that the question is asking for.
Figure out how many miles Andy drives and how many miles Diane drives, then subtract. Andy drives miles in 1
hour and Diane drives miles in 1 hour. Therefore Andy drives 15 − 10 = 5 miles more than Diane in 1 hour.
