Answer:
40 meter, 160 meter and 480 meter.
Step-by-step explanation:
Given:
A 680 m wire is cut into three pieces.
The second piece is 4 times as long as the first
The third piece is 3 times as long as the second
Question asked:
How long is each piece?
Solution:
Let length of first piece of wire =
Then, length of second piece of wire =
Then, length of third piece of wire =
<em><u>As a 680 m wire is cut into three pieces:</u></em>
<em><u /></em><em><u /></em>
<em><u>By dividing both sides by 17</u></em>
<em><u /></em><em><u /></em>
<em><u>Now,</u></em>
The length of first piece of wire = = 40 meter
Length of second piece of wire = =
Length of third piece of wire =
Therefore, length of first, second and third pieces of wire are 40 meter, 160 meter and 480 meter respectively.
