Find D
The label of the quadrilateral are not clear. However, a more complete question illustrates that B and D are opposite sides.
To solve for D, we make use of:
---- opposite 
of a 
quadrilateral
Make D the subject
2 large pizzas and 2 medium pizzas
Over the x-axis: (x, y) (x, –y)
Over the y-axis: (x, y) (–x, y)
Over the line y = x: (x, y) (y, x)
Through the origin: (x, y) (–x, –y)
50 meters per second
3600 seconds per hour
1000 meters per km
50/1000 = 0.05
1/3600 = .0002777
0.05/0.0002777 = 180km per hour
180*4 = 720km in 4 hours
