During a 980. miles cruise, a ship travelled 590 miles in 7 hours first. Then the ship changed its speed for the rest of the trip. If 13 hours were spent on the whole cruise, what was the speed for the rest of the trip? mph​

Explanation:

The average speed of a modern cruise ship is roughly 20 knots (23 miles per hour), with maximum speeds reaching about 30 knots (34.5 miles per hour).

980-590 = 390 miles remaining
13-7 = 6 hours remaining
Miles/hours gives miles per hour for rest of trip therefore 390/6 = 65mph.
