If the average rate of hair growth is 2.5 centimeters every 2 months, then the rate per month is 2.5/2 = 1.25 centimeters.
To calculate how many months it will take to grow 22.5 centimeters of hair, we divide the total length of hair by the rate per month:
22.5 / 1.25 = 18
Therefore, it will take 18 months to grow 22.5 centimeters of hair at the average rate of 2.5 centimeters every 2 months.
The average rate of hair growth is 2.5 centimeters every 2 months. At that rate, how
many months will it take to grow 22.5 centimeters of hair?
