Answer:
It takes 1.77 hours for the population to double.
Step-by-step explanation:
Equation for population growth:
The equation for population growth, after t hours, with a growth rate parameter of r, as a decimal, is given by:

Growth rato parameter of 48% per hour
This means that
. So



How many hours does it take the size of the sample to double?
This is t for which P(t) = 2P(0). So







It takes 1.77 hours for the population to double.
