Question

a copper wire was length 240 m long after 60 m was cut off it was twice the length of steel wire how long was the copper wire than the steel wire in the begining​

Answer 1

Copper wire was 150 m long than steel wire at the beginning.

Step-by-step explanation:

Given:

Length of Copper wire =240 m

Let the length of the steel wire in the beginning be 's'.

Solution:

Now given that;

after 60 m was cut off it was twice the length of steel wire

So we can say that;

Length of Copper wire after 60 m was cutoff =$240 -60 = 180$

So we can say that;

$2s=180$

Dividing both side by 2 we get;

$\frac{2s}{2}=\frac{180}{2}\\\\s=90\ m$

Length of the steel wire in the beginning = 90 m

We need to find how long copper wire was than steel wire in the beginning.

So we will now subtract length of steel wire from length of the copper wire.

Difference between the length = $240 -90 =150\ m$

Hence Copper wire was 150 m long than steel wire at the beginning.

Answer 2

a copper wire is 240

the steel wire is 60

240-60=180ans
