Answer:
a. 70° F b. 0.17min
Explanation:
The fahrenheit scale to time can be given with the following mathematical relation
[tex]\frac{f2-f0}{f1-f0} =\frac{t2-t0}{t1-t0}[/tex]
f2=?
f0=10° F
f1=40° F
t2=1min
t0=0
t1=1/2min
[tex]\frac{f2-10}{40-10} =\frac{1-0}{.5-0}[/tex]
[tex]\frac{f2-10}{30} =\frac{1}{.5}[/tex]
f2-10=60
f2=70° F
b. Goin by the previous relation
[tex]\frac{f2-f0}{f1-f0} =\frac{t2-t0}{t1-t0}[/tex]
[tex]\frac{40-10}{20-10} =\frac{.5-0}{t1-0}[/tex]
30/10=0.5/t0
30t0=5
t0=1/6
t0=0.16666666666666666666666666666667
t0=0.17min
from this, it can concluded that temperature outside increases with time
