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?

A. 2 hours
B. 3/4 hour
C. 1 1/4 hours
D. 5 3/4 hours

Answer 1

i just took the test and the correct answer is :A. 3/4 hour

Answer 2

3 1/4 hours = 3 + 1/4 = 3 + 0.25 = 3.25. 2 1/2 hours = 2 + 1/2 = 2.5. To find out how much travel time can be saved by taking the express, simply subtract its travel time (which is shorter) from the regular's one. So 3.25 - 2.5 = 0.75 or 3/4. So the answer is B.
