Cars arrive at a toll booth according to a Poisson process with mean 50 cars per hour. Suppose the attendant makes a phone call. How long, in seconds, can the attendant's phone call last if the probability is at least 0.8 that no cars arrive during the call? (Round your answer to the nearest integer.)
