N - x 2) 3 students in a dormitory of 100 spread a rumor about the suspension of classes. After 2 minutes, 10 students heard the rumor. If the spread of the rumor per unit of time is jointly proportional to he number of students who heard the rumor and the number of students who haven't yet heard the rumor, determine how long it would take for 80 students to hear the rumor. Determine also the number of students who will hear the rumor in 10 minutes later.
