Question

An electric wire of length 756 metres ran across 15 poles placed at equal distances.
Find out at what distance, were the poles from each other? Also, find the length of the
wire left.​

Answer 1

Answer:

length of electric wire=756

no of poles=15

so we devide 756÷15

to know the length of wire between 2 poles

756÷15

=50.4m

Answer 2

Answer:

• Distance between every pole is 50 m.
• Length of electric wire left is 6 m.

Step-by-step explanation:

Given that:

• An electric wire of length 756 metres ran across 15 poles placed at equal distances.

To Find:

• Distance between the poles.
• Length of wire left.

Solution:

Length of electric wire = 756 m

Number of poles the wire ran across = 15 poles

Distance between every pole = (756 ÷ 15) m

Process:

$\sf\qquad\underline{\;\;\;\;\;\;\;\;50\;\;\;\;\;\;\;}\\ \begin{array}{cc} \sf 15 )&\sf \ 756\\&\underline{\sf -75\downarrow\;\;} \\ & \sf x\;x\;6\\&\underline{\sf\;\;\;\;\;-0\;\;} \\ & \sf \;\;\;\;\;6\end{array}$

Hence,

• Quotient = 50
• Remainder = 6

Therefore,

• Distance between every pole = 50 m
• Length of electric wire left = {756 - (15 × 50)} m = (756 - 750) m = 6 m
