Answer:

B) 23 hours

Step-by-step explanation:

He already traveled 720 miles in 12 hours.

His average speed is (720 miles)/(12 hour) = 60 mph

The entire trip is 2100 miles. He already traveled 720 miles.

2100 miles - 720 miles = 1380 miles.

The time it takes to travel 1380 miles at 60 mph is:

(1380 miles)/(60 mph) = 23 hours

Answer: B) 23 hours
