Question

there are 8 equal spaced lamp posts on a straight road. if the distance between the first post and the last post is 73m 50cm. what is the difference between any two post placed one after the other

Answer 1

distance between first and last post=7350 cm
A------B------C------D------E------F------G------H
∴distance between any two post= 7350 cm ÷ 7
                                                   = 1050 cm

Answer 2

Answer:

10 m 50 cm

Step-by-step explanation:

Here, a number of lamp posts are present on a straight road such that they are equidistant from each other,

Thus,

$\text{The distance between any two successive posts}=\frac{\text{Distance between first and last posts}}{\text{Number of posts}-1}$

Given,

Distance between first and last posts = 73m 50cm = 7300 + 50 = 7350 cm,

And, number of posts = 8,

$\implies \text{The distance between any two successive posts}=\frac{7350}{7}$

$=1050\text{ cm}$

= 10 m 50 cm
