To be honest I’m not sure! But I also would like to know the answer to this question if you figure it out let me know! Good luck
The speed is the ratio between the distance and the time:

Data:
d=6343miles
t=9h

Then, the plane traveled at a speed of 704.77 miles per hour.
DB+ DC= 32
AC+ AC =24
32+24
56
The answer is the 1st graph. This is because a square have 4 sides and it is all the same. on the x axis (Side length) when it is 4 the perimeter (Length around the outside) will be 4 x 4 which is 16.
Hope this helps?
