This "road" they are running is basically an L-shape, and combined with the direct distance from start to end forms a triangle. This triangle has a hypotenuse of 13 (since the direction of the road changes from south to west, we can pretty much assume that it is a right triangle with legs of 5 and X.)
So to find X, we use the Pythagorean Theorem.
a²+b²=c²
(5)²+X²=13²
25+X²=169
X²=144
Distance cannot be negative, so we know that X=12. This is the length of the remainder of the road.
To find total distance, just add the two lengths of road together.
5+12=17

Answer:
A)4
Step-by-step explanation:
Assuming all edges are integral values
The most basic right angles triangle with integral edges is
(3,4,5)
as it obeys pythogores theorem
which is
Now, double each edge,it will still remain a right angled triangle since it will still obey pythogores theorem
so the edges are (4,6,10)
⇒4 cm is the short leg of a integral right triangle with hypotenuse 10 cm
