Temperature for 6 days The average was +10 degrees. On the seventh day, the temperature was +8.6 degrees. Find the average temperature over 7 days.

If the average temperature for 6 days was + 10 °, and for the seventh – + 8.6 °, then we determine what the total temperature was during these seven days.

6 * 10 + 8.6 = 60 + 8.6 = 68.6 (gr.) – the total temperature for 7 days is equal.

Let’s determine the number of days during which the temperature was measured.

6 + 1 = 7 (days) – the number of days.

If we have a total temperature for 7 days, which is 68.6 °, then we can determine what the average temperature was during these 7 days.

68.6 °: 7 = 9.8 ° – the average temperature is equal.
