Two kinds of bacteria are found in a sample of tainted food. It is found that the population size of type 1, N1 and of type 2, N2 satisfy the equation dN/dt=-0.1/N1 dN/dt=0.7/N2 N1 is equal to 1000 at time equal to zero, while N2 is equal to 30 at time equal to zero. Then the population sizes are equal N1 = N2 at what time? (4 decimal places)

Question
Two kinds of bacteria are found in a sample of tainted food. It is found that the
population size of type 1, N1 and of type 2, N2 satisfy the equation
dN/dt=-0.1/N1
dN/dt30.7/N2
N1 is equal to 1000 at time equal to zero, while N2 is equal to 30 at time equal to zero.
Then the population sizes are equal N1 = N2 at what time? (4 decimal places)
