If Honolulu, Hawaii's average temperature in the spring is 81 degrees F and Juneau, Alaska's is 115 degrees F colder than twice of Honolulu's temperature, you need to double Honolulu's temperature and subtract Juneau's temperature to determine the average spring temperature in Juneau.

This would result in the following solution:

81 x 2= 162 (Honolulu's temperature doubled)

162-115 (minus the 115 degree difference)= 47 (results in the average temperature)

47 degrees F is the average spring temperature in Juneau, Alaska based on the information provided.

If Honolulu can be 81 degrees, then Juneau is 2(81) - 115, according to the way your problem reads.

Because Juneau is AT LEAST 2 times Honolulu's temp, which is 162 degrees, minus the 115 degree colder (thus we subtract).

So then Juneau is at least 47 degrees f.

Make sure to include the "at least" phrase, as this answers your question completely.  Good Luck.
