if a pole is set every 30 meters how many poles do you need for a mile?

Answer 1

Assuming you place a pole at the start, you need 54 poles.

1 mile = 5280 ft = 63360 in = 160934.4 cm = 1609.344 m

1609.344 / 30 = 53.6448

You need 53 poles, plus a pole at the beginning of the mile, for a total of 54.

Answer 2

So far the math from everyone else seems correct. But their answer [conclusion] is incorrect because not enough information is given in your problem.

1.00000 miles = 1609.3440000 meters

1609.3440000 divided by 30 meters = 53.6444666...

Some say 53 poles. They are correct, depending on the additional information.

Some say 54 poles. They are also correct, depending on the additional information.

How can they both be right?

They are failing to consider and state whether there is a pole at the beginning, or is the first pole set at 30 meters.

If you ever build a fence, you will have a pole at the beginning!

The solution is this:

If you start with a pole at the 0.000001 meter mark, then there will be 54 poles: one at the beginning and then 53 more poles set 30 meters apart.

If you do not place the first pole until the 30.000000 meter mark, then there will be 53 poles: nothing for the first 29.99999 meters and then the first pole at 30.0000000 meters, and then 52 more poles set 30 meters apart..

Change the question to setting poles every three [3] feet over a fifteen [15] foot distance.

1 1 1 1 1
1 2 3 4 5 6 7 8 9 0 1 2 3 4 5

x x x x x x first pole at 0.000001 foot = 6 poles

x x x x x first pole at 3.0000001 feet = 5 poles

So, the correct answer depends on whether a person is going to start with a pole, or a 30 meter gap?

Answer 3

Between poles is 30 meters apart- 30 X 39.375(inches) =1,181.25 inches

1 mile = 5280 feet X 12 inches = 63,360 inches

63,360 / 1,181.25 = 53.63809523.

1 pole at the beginning, + 53 from pole to pole at 30 meter, last
poles with 62 feet, 9+3/4 inches to meet the mile mark.

So it takes 55 poles. (You might want to adjust the pole to pole to 29.799 meters to make it evenly spaced.)

Answer 4

About 55

Answer 5

A mile is about 1,600 meters. So there could be 53 poles stretched in 1,590 meters, plus an extra space of 10 meters.

Answer 6

You need only 53 poles and a third of another pole to cover the distance.

Answer 7

A mile is 1.6 kilometres or 1600 metres.

Divide 1600 by 30 and you get 53.3.

You would need 53 poles spaced 30 metres apart to reach one mile.

Answer 8

5280 feet equals one mile

5280 feet equals 1609.34 meters rounded to two decimal places

1609 divided by 30 equals 53.63333333

53.63 poles rounded to two decimal places

since a pole is set every thirty meters it will take 53.63 poles to complete a mile.

Answer 9

30 metres=3000 cm
3000/2.54 inches=3000/(2.54*12) ft
no fo poles=5280*2.54*12/3000=53+1=54 poles the fraction being neglected

Answer 10

54 poles bcoz you need an extra pole to begin with
