S=d/t
s=40/4
s=10
Therefore the average speed of the football is 10yd/s!

Answer:
A. 2,3,4
D 3,4,5
Step-by-step explanation:
In order for segment lengths to be able to form a triangle, the sum of the shortest two must exceed the longest.
A. 2,3,4 . . . 2 + 3 > 4 . . . can make a triangle
B. 2,3,5 . . . 2 + 3 = 5 . . . not a triangle
C. 2,3,6 . . . 2 + 3 < 6 . . . not a triangle
D 3,4,5 . . . 3 + 4 > b . . . can make a (right) triangle
E. 3,4,8 . . . 3 + 4 < 8 . . . not a triangle
The length of the arc intercepted by a central angle is the ratio of the angle to 360 degrees times the circumference. From the given values above,
S = (30° / 360°) x 2 x π x (6 ft)
S = π
The angle intercepted an arc which measures π feet. The answer is letter A.
