Let the time spent verifying old reservations be x hours. Then, entering new reservations took 2x hours, and calling to confirm reservations took 1.5x hours. The total time is x + 2x + 1.5x = 9.45 hours. Solving for x gives x = 2.1 hours. Therefore, entering new reservations took 2x = 2 * 2.1 = 4.2 hours.
