The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?

₋₋₋₋₋₋₋₋ °F per hour

Answer:

-3.5

Step-by-step explanation:

As there was a total change of -21, that would be the first part of your equation:

-21

As 6 hours had passed and you are trying to find the mean, your equation would now be:

-21 ÷ 6 = ?

Now you can solve the equation, and the answer is -3.5°F per hour.

The mean change in temperature per hour is -3.5 °F.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The total change in the outdoor temperature over 6 hours was -21°F

So, in one hour the mean change in temperature

= -21/6

= -3.5 °F

Hence, the mean change in temperature per hour is -3.5 °F.
