Answer:
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
Answer:
See below
Step-by-step explanation:
Part A
The rate of decrease:
- 7° F° in 3 hours ⇒ 7/3° F/h ≈ 2° F/h
Part B
Change after 5 hours:
- 5*2° F = 10° F decrease
