Question

Hair grows at a rate of around 5*10^-2 inches per month, whereas nails grow around 1*10^-2 inches per month. Use these numbers to complete the sentence below.

Nails grow about____times as fast as hair does.

2.5 times
5 times
10 times
20 times

Answer 1

Nails grow about 10 times as fast as hair does.

Step-by-step explanation:

Nails grow about 10 times as fast as hair does.

To calculate this, we can compare the growth rates of hair and nails:

1. Hair grows at a rate of around 5*10^-2 inches per month.
2. Nails grow at a rate of around 1*10^-2 inches per month.

To find out how many times faster nails grow compared to hair, we can divide the growth rate of nails by the growth rate of hair: 1*10^-2 inches per month / 5*10^-2 inches per month = 1/5 = 0.2

Therefore, nails grow about 0.2 times as fast as hair does.
