Question

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 bus

Answer 1

3/4 of an hour

Explanation:

One bus takes 3.25 hours to get to its destination, the other bus takes 2.5 hours to get to the same destination. To find out how much time we save, we can subtract the latter amount from the first value.

Decimal Form: 3.25 - 2.5 = 0.75

Fraction Form:

3 1/4 - 2 1/2 = x

Change the 2 1/2 into a common denominator, which is 2 2/4

3 1/4 - 2 2/4 = x

We can change to improper fraction from

13/4 - 10/4 = x

3/4 = x

We save 3/4 of an hour by taking the express bus, or 45 minutes.
