Answer:
A
Step-by-step explanation:
We know that the growth of a linear function will always be constant. So, that eliminates B and C.
A quadratic function can be a function such as 
, or 
, etc.
An exponential function wouldn't be , it would be 
! Or 
, or 
, etc. Therefore, D is eliminated.
So, the answer is 
and we're done!
Average speed = (total distance covered) / (time to cover the whole distance)
Total distance = (516 + 368) = 884 yards
Total time = (6 + 4) = 10 minutes
Average speed = (884 yards) / (10 minutes)
Average speed = 88.4 yards/minute (C)
Other ways to write the same speed:
-- 4.42 feet/second
-- 265.2 feet/minute
-- 53.04 inches/second
-- 5,304 yards/hour
-- 3.014 mph (rounded)
-- 810.07 furlong/fortnight
B. 12 would be your answer
