An average person's hair grows at a rate of 19 cm per year. How fast in inches per month does the
average person's hair grow? Show all work for solving. Round your answer to the nearest tenth. 1 cm = 0.39 inches

answer:

0.6 inches

Step-by-step explanation:

1 year = 12 months

If an average person's hair grows at a rate of 19cm per year (per 12 months), then it grows at the rate of

19 / 12 = 1.583 cm

Next step is to convert 1.583 cm to inches.

If 1 cm = 0.39 inches,

Then, 1.583 cm = (1.583 X 0.39) inches = 0.617 inches

We round up 0.617 to 0.6.
