Question

six fence post are place 5 meters apart what is the distance from the first to last post​

Answer 1

Given,

Six fence post are placed 5 meters apart

To find,

Distance between the first and last post.

Solution,

Distance between Fence post 1 and fence post 2 is 5m.

Similarly all other adjacent posts will have 5m between them.

Number of such adjacent pairs will be = $6 - 1 = 5$

Distance for 1 adjacent post is 5m.

Distance for 5 such adjacent pair is = $5*5m = 25m$

Therefore distance from the first to last post​ is $25m$.

Answer 2

Six fence post are place 5 meters apart = 25m

Explanation:

Given Data:

No of fence placed = 6

Distance between 2 fences = 5m

Now,

$d = n-1$

Where d = Number of gaps between the first and the last fence

n = No. of fence placed

So,  

$d = 6-1 = 5$

D = d x Distance between 2 fences

$D = 5 x 5$

$D = 25m$
