Answer:
When you come to an intersection, follow this important rule (left, right, left). Look to the left first because vehicles coming from the left are closer to you. Look to the right. Take one more look to the left before you pull out.

Answer:
See explaination and attachment for theprogram code and output.
Explanation:
matlab program:
x1(1)=0;
y1(1)=0;
x2(1)=0;
y2(1)=0;
x3(1)=0;
y3(1)=0;
for i=1:10
x1(i+1)=0.5*x1(i);
y1(i+1)=0.5*y1(i);
x2(i+1)=0.5*x2(i)+0.25;
y2(i+1)=0.5*y2(i)+(sqrt(3)/4);
x3(i+1)=0.5*x3(i)+0.5;
y3(i+1)=0.5*y3(i);
end
figure
hold on
plot(x1,y1,'*')
plot(x2,y2,'*')
plot(x3,y3,'*')
hold off

Answer:
a. 0.28
Explanation:
Given that
porosity =30%
hydraulic gradient = 0.0014
hydraulic conductivity = 6.9 x 10⁻4 m/s
We know that average linear velocity given as
![v=\dfrac{K}{n_e}\dfrac{dh}{dl}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7BK%7D%7Bn_e%7D%5Cdfrac%7Bdh%7D%7Bdl%7D)
![v=\dfrac{6.9\times 10^{-4}}{0.3}\times0.0014\ m/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B6.9%5Ctimes%2010%5E%7B-4%7D%7D%7B0.3%7D%5Ctimes0.0014%5C%20m%2Fs)
![v=3.22\times 10^{-6}\ m/s](https://tex.z-dn.net/?f=v%3D3.22%5Ctimes%2010%5E%7B-6%7D%5C%20m%2Fs)
The velocity in m/d ( 1 m/s =86400 m/d)
v= 0.27 m/d
So the nearest answer is 'a'.
a. 0.28
