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 :)

To find out how much travel time can be saved by taking the express bus, we need to subtract the travel time of the express bus from the travel time of the regular bus.

Travel time of regular bus = 3 1/4 hours
Travel time of express bus = 2 1/2 hours

To subtract fractions with different denominators, we need to find a common denominator. The least common denominator for 4 and 2 is 4.

3 1/4 - 2 1/2 = (3*4 + 1)/4 - (2*2 + 1)/2 = (13/4) - (5/2) = 13/4 - 10/4 = 3/4

Therefore, the travel time that can be saved by taking the express is 3/4 hour.

So the answer is:
B. 3/4 hour

To find out how much travel time can be saved by taking the express bus, we need to subtract the travel time of the express bus from the travel time of the regular bus.

The regular bus takes 3 1/4 hours to reach its destination, which is the same as 3 hours and 15 minutes.

The express bus takes 2 1/2 hours to make the same trip, which is the same as 2 hours and 30 minutes.

To find the difference between the two travel times, we subtract the time of the express bus from the time of the regular bus:

3 hours 15 minutes - 2 hours 30 minutes = 45 minutes

So, taking the express bus saves 45 minutes of travel time.

To convert this to a mixed number, we divide 45 minutes by 60 (the number of minutes in an hour):

45 minutes ÷ 60 minutes/hour = 3/4 hour

Therefore, the correct answer is B. 3/4 hour.
