At 1mph, 244 miles will take 244 hours to travel. At 60mph, 244 miles will take 4.0666... hours to travel. At the speed of light, 244 miles will take 1.31 milliseconds to travel.

The time (in hours) that it takes to travel 545 miles depends entirely upon the rate (speed) of travel. Thus, on a bicycle at the rate of 10 miles per hour, it will take 54.5 hours to travel the full distance of 545 miles.

I think the question should say "How many hours will it take to travel 10 miles at 24 miles an hour?" If so, the answer is 10/24 hours. That's 25 minutes.
