One model for the spread of a rumor is that the rate of spread is proportional to the product of the fraction y of the population who have heard the rumor and the fraction who have not heard the rumor.
write a differential equation that is satisfied by y
a small town has 3,500 inhabitants. at 8 am, 280 people have heard a rumor. by noon half the town has heard it. at what time will 90% of the population have heard the rumor? (do not round k in your calculation. round your final answer to one decimal place.)
