Answer:

The temperature at 8:00 A.M. was 18º C.

Explanation:

Given that at 2:00 P.M., a radio announcer reported that the temperature was 25 ° C, and that from 11:00 A.M. to 2:00 P.M. the temperature had risen 4 ° C, while from 8:00 A.M. to 11:00 A.M. the temperature had risen 3 ° C, to determine what was the temperature at 8:00 A.M. the following calculation must be performed:

25 - 4 - 3 = X

21 - 3 = X

18 = X

Thus, the temperature at 8:00 A.M. was 18º C.
