320 because you added the two numbers to get the total.
I don't really get what the "35,000 feet university sea level" part is saying, but without it, the answer would be:
3.5 x 550 = 1,925
The plane traveled 1,925 miles.
And with it, the answer would be:
3.5 x 550 = 1,925
35,000 ft = 6.6 mi
1,925 + 6.6 = 1,931.6
The plane traveled 1,931.6 miles.
Hope this helped a little at least.
