    1°C

    Step-by-step explanation:

    The inicial temperature at 09:00 was - 3°C.

    The changes in temperature in each of the six hours were:

    first hour: - 2°C

    secondhour: + 3°C

    third hour: + 2°C

    fourth hour: - 1°C

    fifth hour: + 4°C

    sixth hour: - 2°C

    So, the temperature at 15:00 is the sum of the inicial temperature and all of these changes:

    Temperature at 15:00 = - 3°C - 2°C + 3°C + 2°C - 1°C + 4°C - 2°C = 1°C
