You are given the problem in miles per hour and would like to convert it to miles per second. So we must use a conversion factors (1)from hours to minutes and (2)minutes to seconds.
%2855+miles%29%2F%281+hour%29 x %281+hour%29%2F%2860+minutes%29 x %281+minute%29%2F%2860+seconds%29

=%2855+miles%29%2F%281+hour%29 x %281+hour%29%2F%2860+minute%29 x %281+minute%29%2F%2860+seconds%29

=%2855+miles%29%2F%2860+x+60+seconds%29

=%2855+miles%29%2F%283600+seconds%29=%2811+miles%29%2F%28720+seconds%29= .01527778 mi/sec
