a pole of height 3 m is struck by a speeding car and breaks into two pieces such that the first piece is is one by two two of the second find the length of both piece

Step-by-step explanation:
Proper question Please
Hint: We first assume the length of the pieces of the pole. We find the total which is equal to 3 and then solve the equation to find the solution of the variable.
Complete step by step solution:
A pole of height 3 metres is stuck by a speeding car and breaks into two pieces such that the first piece is 12 of the second.
Let us assume the length of the first piece as x metres. It is given that the first piece is 12 of the second which means the second piece is twice the first.
Therefore, the length of the second piece is 2x metres.
The total of these two pieces will be 2x+x=3x meters.
Now we equate it with a total length of 3 metres to find the equation of 3x=3.
Dividing both sides with 3 we get 3x3=33⇒x=1.
Therefore, the length of the first piece is 1 meter. The length of the second piece is 2 meters.
Note:
We also could have taken the length of the second piece as x to find the length of the first piece to be x2. The inverse relation will also give the same result.
