Weekly Temperature Grid Average

A 2D array Temps stores two readings (morning, afternoon) for each of 3 days: Temps[1] is the morning row, Temps[2] is the afternoon row, and the second index is the day. Read all six readings, then output the overall average of all six, rounded to 1 decimal place.

Input: 6 real numbers (row by row: 3 morning readings, then 3 afternoon readings). Output: Average temperature: <average to 1 dp>.

Example:

Input:  10
        12
        14
        18
        20
        22
Output: Average temperature: 16
