Answer:
35 minutes
Step-by-step explanation:
Beth left for the airport 105 before her flight was scheduled to leave, and she arrived at the airport 70 minutes before her flight was scheduled to leave.
The difference between when she left and when she arrived will be how long her drive was.
Subtract how many minutes early she was before when she arrived, from how many minutes early she was when she left.
left-arrived
She left with 105 minutes to spare, and 70 minutes left when she arrived.
105-70
35
The drive to the airport took 35 minutes
