Note those are impossible speeds for aircraft carriers.

Ignoring that fact....

The first carrier travels for 2 hours at 60 mph, traveling 120 miles, before the second carrier starts.

The second carrier overtakes the first at the rate of 80-60=20mph.

The number of hours it takes to make up 120 miles at 20mph is 120/20=6.

6 hours after 9:00 AM is 3:00 PM.

ANSWER: 3 pm
