Explanation:

Step1: Calculate total delay

Add the two delays together. $45 + 35=80$ minutes.

Step2: Convert total delay to hours and minutes

Since 60 minutes = 1 hour, 80 minutes = 1 hour and 20 minutes.

Step3: Subtract total delay from actual take - off time

The flight took off at 2:45 pm. Subtract 1 hour and 20 minutes. 2:45 pm - 1 hour = 1:45 pm, and 1:45 pm - 20 minutes = 1:25 pm.

Answer:

1:25 pm
