Step-by-step explanation:
Answer:
8 miles
Step-by-step explanation:
Given
<em>Represent the police station with P, Library with L; Fire station with F</em>
<em>The first statement can be represented as:</em>
<em></em>
<em>The second can be represented as:</em>

Required
Determine the distance between the police station and the fire station (P - F)
--- (1)
--- (2)
Substitute 5 for L - P in (1)

Add 3 to both sides




The function is:
B ( t ) = 4 * e^(0.8 t)
4 * e^(0.8 t) = 400
e^(0.8 t) = 400: 4
e^(0.8 t) = 100 / ln
ln e^(0.8 t) = ln 100 ( and since: ln e = 1 and ln e^x = x * ln e )
0.8 t = 4.6
t = 4.6 : 0.8 = 5.76 ≈ 6
Answer:
D ) 6 hours.
