A driving school has 600 trainees. On one particular day, a small group of trainees thought they heard their instructor said that no one one had managed to pass for their advanced driving techniques course. 24 hours later, a survey of the entire student population revealed that by then 40 students had heard this rumour. The rumour spreads according to the equation, R(t)=600/〖1+75e〗^kt where R(t) is the number of trainees who had heard the rumour, t is the time in hours after the first group of trainees though they heard their instructor and k is a constant.
Find the time needed for 90% of the trainee population to have heard the rumour.
