The fastest a human has ever run is 27 miles per hour. How many miles per minute did the human run

2 answers:

8 0

(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.

27 miles per 1 hour
27 miles per 60 minutes
per 1 minute = 27/60 = 9/20 mile

Answer:

Step-by-step explanation:

You could talk about how how or low it goes.

For instance: if the graph was going very high then suddenly low you could say that it was going very high until it suddenly dropped.

What are the endpoint coordinates for the midsegment of △BCD that is parallel to BC?

natulia [17]

Answer:

<em>The endpoint coordinates for the mid-segment are: $(-2,-1)$ and $(1,0)$ </em>

Step-by-step explanation:

According to the given diagram, the coordinates of the vertices of $\triangle BCD$ are: $B(-3,1), C(3,3)$ and $D(-1,-3)$

Now, the endpoints of the mid-segment of $\triangle BCD$ which is parallel to $BC$ will be the mid-points of sides $BD$ and $CD$ .

<u>Formula for the coordinate of mid-point</u> : $(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})$ , where $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ are two endpoints.

So, the mid-point of $BD$ will be: $(\frac{-3-1}{2},\frac{1-3}{2})=(\frac{-4}{2},\frac{-2}{2})=(-2,-1)$

and the mid-point of $CD$ will be: $(\frac{3-1}{2},\frac{3-3}{2})=(\frac{2}{2},\frac{0}{2})=(1,0)$

Thus, the endpoint coordinates for the mid-segment of $\triangle BCD$ that is parallel to $BC$ are $(-2,-1)$ and $(1,0)$
