Answer:
The first car is traveling at a speed of
s1=62 mi/hr.
The second car is traveling at a speed of s2=67 mi/hr.
Step-by-step explanation:
Let t be the amount of time the cars are traveling
s1=248/t and s2=268/t
We are told:
s1=s2-5
That is
248/t=268/t-5
⇒248=268- 5t
⇒5t=20
⇒t=4
s1=248/4=62
s2=268/4=67

Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
