Yes. Your original plan, question #3, had you at 30,000' flying 300kts
TAS. Spinning the winds (280°/22 kts) gives you 22 kts of headwind and a
resultant ground speed of 278 kts on a course of 275°T.
After your instructor changed the plan you chose to go to 39,000', which gave
you an OAT of -75° and winds at 320°/65 kts. A CAS of 190 kts at this altitude
and temperature gives you a TAS of 333 kts. Spinning the winds gives you 45
kts of headwind resulting in a ground speed of 288 kts on a course of 275°T.
Therefore going higher, in this case, gets you to San Diego faster.
