There are about 6 billion people on Earth. If they all lined up and held hands, how long of a line would they form in km? (Assume each person is 1 meter apart.)

Question

There are about 6 billion people on Earth. If they all lined up and held hands, how long of a line would they form in  km? (Assume each person is 1 meter apart.)

anonymous · Answer

Assume that there is 1 meter between each person? or each person's span is 1 meter?

anonymous · Answer

6 billion -1 meter

anonymous · Answer

1 meter apart i think

anonymous · Answer

Man, that turned out to be wrong

anonymous · Answer

What is wrong?

anonymous · Answer

the answer.

anonymous · Answer

1 000 000 000 000 is bilion

anonymous · Answer

oh oops XD if each person is separated by a distance of 1 meter, you would need to know the distance of each person's width.  But if 1 meter represents the total distance from left fingertips to right fingertips, myko is correct. 6 billion meters - 1 meter = 599,999,999,999 meters * 1km/1000meters = 599,999,999.999km

anonymous · Answer

right

anonymous · Answer

haha wombat fail XD

anonymous · Answer

I don't know what its asking then because that says its wrong too

anonymous · Answer

If that is wrong, then maybe they mean that there is one meter separating two people, not accounting for the width of their bodies.  In this case, you would need the body width to solve...

anonymous · Answer

So are you saying in that instance, it can't be solved?

radar · Answer

How many meters would a line of three people with spacing of 1 meter between each?  think about it.

anonymous · Answer

Well, if that is all the information given, then I think it is unsolvable.. However, it all depends on what they mean by 1 meter apart

anonymous · Answer

radar, doesnen't it depend on how wide the person is

radar · Answer

I guess that is why you are subtracting the 1 meter "hand slapping forehead"  Yes, that would come into play the width of the person, I guess you would assume some reasonable average figure.

anonymous · Answer

If they do not provide you with a width of the person and the 1 meter represents the distance BETWEEN each person, it is not solvable.

radar · Answer

6,000,000,000 - 1=5,999,999,999 meters  for km 5,999,999.999

radar · Answer

Ignoring the width of individuals. lol

anonymous · Answer

Its still wrong

anonymous · Answer

I guess i'll have to email my professor
