A person's hair length is proportional to the number of years it has been growing. After 2 years a person's hair grows 8 inches. The longest moustache on record was grown by Sain of India. Sain grew his moustache for 17 years. How long was each side of his moustache?
17/2 = 8.5
8.5 * 8 = ?
To find the length of each side of Sain's moustache, we can set up a proportion using the information given.
Let's define the variables:
- Let x be the length of each side of Sain's moustache.
- Let y be the number of years it takes for Sain's moustache to grow x inches.
We know that a person's hair length is proportional to the number of years it has been growing. So, we can set up the proportion:
2 years / 8 inches = 17 years / x inches
To solve for x, we can cross-multiply and then divide:
2 * x = 8 * 17
2x = 136
x = 68
Therefore, each side of Sain's moustache was 68 inches long.
