Martin owns a single cab and license. He lists his telephone number in the yellow pages, and takes calls (for cab ride) on his cell phone while driving. On average he receives a call every 1.25 hours. Service to a customer is divided into two parts: . An average drive time to pick-up a passenger is 13 min. . An average drive time to drop-off a passenger is 17 min. (this time includes the time the passenger takes to pay Martin). Martin always carries one passenger at a time. When Martin is busy offering a ride, a new calling customer waits as long as necessary to get a ride from Martin. What is the average time from a customer's call until Martin picks up that customer?
