Since the limit becomes the undetermined form

it means that both polynomials have a root at
. So, we can fact both numerator and denominator:


So, the fraction becomes

Now, as x approaches 1, you have no problems anymore:

You can't convert miles into gallons those are two different units of measurement.
I can’t really see it well
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.
