The beginning, middle and end part of the song is 40, 120 and 240 seconds respectively
<h3 /><h3>How to find equation of the unknown</h3>
let
- x = end part
- Beginning = 1/6x
- Middle = 1/2x
- Total = 400 seconds
x + 1/6x + 1/2x = 400
(6x+x+3x) / 6 = 400
10/6x = 400
x = 400 ÷ 10/6
x = 400 × 6/ 10
= 2400 / 10
= 240 seconds
Therefore,
End part = x
= 240 seconds
Beginning = 1/6x
= 1/6 × 240
= 40 seconds
Middle = 1/2x
= 1/2 × 240
= 120 seconds
Complete question:
