P(t)=100t(0.78t)

Estimate how fast the population is changing 11 days after the onset of the illness.

The rate of change of the population 11 days after the onset of the illness is approximately 8.8.
I suspect a typo, since such spread is usually an exponential function.. But, as written,
P'(t) = 156t
so P'(11) = 1716
dP/dt = lo0.78 * 100
