Time taken by a regular bus to reach its destination = 3 1/4 hours = 13/4 hours Time taken by the express bus to make the same trip = 2 1/2 hours = 5/2 hours Time that can be saved by taking the express bus = (13/4) - (5/2) hours = (13 - 10)/4 hours = 3/4 hours So 3/4 hours can be saved by taking the express bus rather than the regular bus. The correct option among all the options given in the question is option "C". I hope the procedure is simple enough for you to understand.
