Answer:

6N = T

They will take 96 minutes to add 16 seats.

Step-by-step explanation:

In the factory, the workers add bicycle seats at a rate of 2 seats every 12 minutes.

If the number of seats they add is N and the number of minutes it takes is T, then they are proportional i.e. N ∝ T.

⇒ N = kT ........... (1)

Now, N = 2 for T = 12 minutes.

So, from equation (1), 2 = 12k

⇒ k = \frac{1}{6}

Therefore, the equation (1) becomes N = \frac{1}{6}T

⇒ 6N = T ......... (2)

Now, for N = 16, from equation (2) we get,

T = 16 × 6 = 96 minutes.

Therefore, they will take 96 minutes to add 16 seats. (Answer)

900 rabbits represent 500% of last year population

Last year population represent 100%

so

using proportion

Find out how many rabbits represent a percentage of 100%

\frac{900}{500\%}=\frac{x}{100\%}\\\\x=900(100)/500\\\\x=180\ rabbits
