The answer is 3km as there is 9 secs between it and distance = time/3 and 9/3 =3 so distance =3
Answer:
13
Step-by-step explanation:

Hope this helps!
We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=

. Hence CM=GC+GM=3*

. Now, since GM is normal to AB, we have by the pythagoeran theorem that:

Hence, we calculate from this that AC^2= 28, hence AC=2*

=BC. Thus, the perimeter of the triangle is 2+4*

.
It’s A, Because if you do KCF (Keep Change Flip) It would be 1/6 X 7/5.
