3. The outside temperature decreases by 7°F in 3 hours.
Part A
How would you represent the
temperature change as a unit rate?
Express your answer as an integer.
Part B
If the temperature continues to
decrease at this rate, what will be the
change in temperature after 5 hours?

A)  2f / hour

B) 10 f

Step-by-step explanation:

outside temperature decreases by ; 7 F in 3 1/2 hours

a ) represent temperature change as a unit rate

To do this you will need to represent the temperature change per hour

7 f / 3.5 hours

= 7 f / 3.5 = 2 therefore the temperature change as a unit rate = 2f / hour

b) Temperature change after 5 hours

Δ temperature  in 5 hours = temperature change per hour * 5

                            = 2 F * 5 =  10 F

See below

Step-by-step explanation:

Part A

The rate of decrease:

Part B

Change after 5 hours:

the answer is: the length is 5/6 yards.
