Answer:
It would take 90.9 days
Step-by-step explanation:
The sample of the hair considered grows at 0.44mm per day, thus;
0.44mm = 1 day
40 mm = x days
So that, by appropriate deductions,
0.44 × x = 40 × 1
0.44x = 40
Divide both side by 0.44 to determine the value of x;
x =
x = 90.9090909091
Therfer, it would take up to 90.9 days for the hair to measure 40mm from its follicle to tip.
