5. A bus on a regular schedule takes 3 1/4 hours to reach its destination. The express bus takes 2 1/2 hours to make the same trip. How much travel time can be saved by taking the express?
A. 1 1/4 hours
B. 3/4 hour
C. 2 hours
D. 5 3/4 hours
it C right?

I got 3/4 hour because:
3 1/4  2 1/2
13/4  5/2, you must multiple the 5 and 2 by 2 (common demoniator)
13/4  10/4 = 3/4
you could also use percents as well and you will get b
hope this helps :)
