Since the cycle is 20 mph, you then know that you have at least one hour (60min). Then, you have five miles left. You simply divide 5 over 20 (5/20) which will get you 0.25. Well then, what is one fourth of 60min? It is 15 minutes. Lastly, you add 60min to 15min (60 min + 15 min) to equal 75 minutes or 1 hour and 15 minutes.
