The answer is A.
Speed = distance / time
Speed = (4*400) / (6*60) (6*60 to turn minutes to seconds)
Speed = 1600 / 360
Speed = 4.44
Velocity = displacement / time
since she is running in a circle, she stops where she started making he displacement 0
Velocity = 0 / 6*60
Velocity = 0
Answer:
The ratio of boys to girls to 5:7
Let the number of boys be 5x
Let the number of girls be 7x
5x = 30
x = 6
Now just plug in 6 for the x in 7x
and number of girls 7 x 6 = 42
To find the area of the deck, we need to calculate the area of triangle and rectangles
Lets find the area of triangle A
Area of triangle = 
base = 9 and height =10
So area of triangle A =
= 45
Area of rectangle = Base * height
Base of rectangle B = 9ft
Height of rectangle B = 12ft
Area of rectangle B = 9*12 = 108 square feet
Base of rectangle C = 24ft
Height of rectangle C = 22ft
Area of rectangle C = 24 * 22 =528 square feet
Area of the deck = Area of A + area of B + area of C
= 45 + 108 + 528
= 681 square feet
