Determine the average speed of Mr. Ali's journey
To do this, we have to calculate the total distance covered.
i.e.
Distance = Town A to B + Town B to C
The distance between the towns are not given. So, I'll make an assumption.
<em>-------------------------------------------------------------------------------------------------------------</em>
<em>Assume:</em>
<em>Town A to B = 5km</em>
<em>Town B to C = 10km</em>

Average Speed is then calculated as:

SAS similarity
two triangles are similar when they<span> have </span>corresponding<span> angles that are </span>congruent<span> and corresponding sides with identical </span>ratios.
According to our case, <span>the ratios of two pairs of corresponding sides are

Answer:
Same-side Interior Angles theorem justifies ∠ 11 + ∠ 10 =180°
Step-by-step explanation:
To Prove:
∠ 11 + ∠ 10 =180°
Proof:
Consider lines are Parallel,then
Corresponding Angles are Equal
∴ ∠ 10 = ∠ 12 say (equation 1)
Now by Linear Pair postulate we have,
∴ ∠ 11 + ∠ 12 = 180° say (equation 2)
Now by replacing ∠12 by ∠ 10 from equation 1 in equation 2 we get
∴ ∠ 11 + ∠ 10 = 180°
Hence proved the above statement.
10c+25p=400. The c stands for chickens and the p stands for pigs
