Solve the problem.

Between 8:30 a.m. and 9:30 a.m., cars drive through the Cappuccino Express at a rate of 12 cars per hour (0.2 per minute). The following formula from probability can be used to determine the probability that a car will arrive within t minutes of 8:30a.m.

F(t) = 1 - e^-0.2t

Determine how many minutes are needed for the probability to reach 0.6.
