A spacecraft has been travelling for 2yrs 6 months and 14 days.
The distance it had to travel from Earth to a planet was 35 light years.

hello:

so i've got this equation the population is N=20000e^0.5*t where t is the number of years since the start of 1995.
how do you work out how many people there are at the start of 1995? it doesnt work if you let t=1 or 0..
