Answer:6 passengers got off at New Jersey.
Since a bus departed from New York at 11 pm with 44 passengers, and an hour later, a few passengers got off at New Jersey, and the number of passengers who boarded the bus at New Jersey were twice the number of passengers who got off the bus, to determine, if the bus has 50 passengers now, how many passengers got off at New Jersey, the following calculation must be performed:
44 - X + 2X = 50
44 + X = 50
X = 50 - 44
X = 6
So 6 passengers got off at New Jersey.
