Answer:
80 seconds
Step-by-step explanation:
Lets get the negative reciprocal of the slope so we get

Now the equation that is perpendicular is

Lets solve for b by plugging in the point (x,y)=(6,1)

Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.
