Answer:
the runners have gone 20.8 times around the globe all together
Step-by-step explanation:
At the Bostom Marathon, we have a total of
N = 20,000 runners
We know that each runner ran a distance of
d = 26 miles
Therefore, the total distance travelled by all runners combined is:
![D=Nd=(20,000)(26)=5.2\cdot 10^5 mi](https://tex.z-dn.net/?f=D%3DNd%3D%2820%2C000%29%2826%29%3D5.2%5Ccdot%2010%5E5%20mi)
We know that the circumference of the Earth is
![c=2.5\cdot 10^4 mi](https://tex.z-dn.net/?f=c%3D2.5%5Ccdot%2010%5E4%20mi)
Here we want to find how many times around the globe would the marathon runners have gone. This can be found by calculating the following ratio:
![n=\frac{D}{c}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BD%7D%7Bc%7D)
And substituting the values, we find:
![n=\frac{5.2\cdot 10^5}{2.5\cdot 10^4}=20.8](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B5.2%5Ccdot%2010%5E5%7D%7B2.5%5Ccdot%2010%5E4%7D%3D20.8)
So, the runners have gone 20.8 times around the globe all together.
Answer:

Step-by-step explanation:
midpoint=(x1+x2)÷2,(y1+y2)÷2
a(4,15) b(8,1)
x=4+8=12÷2=6
y=15+1=16÷2=8
Answer=(6,8)
