A thief on a bus gets off at a bus stop and walks in the direction opposite to the bus’s travel direction. The bus continues its journey, and a passenger realizes they have been robbed. The passenger gets off at the next stop and starts chasing the thief. If the passenger's speed is twice that of the thief, the bus's speed is ten times the speed of the thief, and the bus takes 40 seconds to travel between two stops, how many seconds will it take for the passenger to catch up with the thief after getting off the bus?
