(27 mi/hr) x (1 hr / 60 min) = (27/60) (mi/min) = 0.45 mile/minute
Using the same kind of calculation, we can see
that the world record times for other distances
correspond to:
200 meters 23.31 mph
400 meters 20.72 mph
800 meters 17.73 mph
1000 meters 16.95 mph
1500 meters 16.29 mph
1 mile (1,609 meters) 16.13 mph
2,000 meters 15.71 mph
10,000 meters 14.18 mph
30,000 meters 12.89 mph
Marathon (42,195 meters) 13.10 mph
Except for that one figure at the end, for the marathon,
which I can't explain yet and I'll need to investigate further,
it's pretty obvious that a human being, whether running for
his life or for a gold medal, can't keep up the pace indefinitely.
Answer:
2.66 or 2 2/3
Step-by-step explanation:
Answer:
7.5 or 15/2
Step-by-step explanation:
x-3x+6=2x-24 -- Combine like terms
-2x+6=2x-24 -- Add 2x to each side
6 = 4x-24 -- add 24 to each side
30 = 4x -- divide by 4
15/2 or 7.5 = x
Answer:
The vertex of the quadratic function is:

Given the function
As the vertex of the form 
is defined as:
As the quadratic function of parabola params are
so
Putting to determine 
Therefore, the vertex of the quadratic function is:
Answer:
11/12
Step-by-step explanation:
7/6= 14/12
8/6= 16/12
the number in between the two is 15/12 then it already shows you what to subtract by (4/12) so 15/12-4/12=11/12
