The growth rate of the duckweed population can be calculated using the formula N(t) = N(0) + (b-d)N(0)t, where N(t) is the population at time t, N(0) is the initial population, b is the birth rate, d is the death rate, and t is the time in weeks. Substituting the given values, N(1) = 50 + (0.4-0.2)*50*1 = 50 + 10 = 60.
