Question

The distance between home and university is 15 3/4 miles . Before Ashley goes to class, she needs to drop off Bernice at elementary school, which is 9 1/8 miles away from their home. Affer she drops off Bernice, Ashley bikes 12 1/3 miles to the university, Compared to going to university directly from home, how much more does Ashley need to travel if she drops off Bernice?

Answer 1

Ashley needs to travel 5 31/24 miles more if she drops off Bernice.

Step-by-step explanation:

To determine how much more Ashley needs to travel if she drops off Bernice before going to the university, we need to find the difference between the distance of going directly to the university and the distance of dropping off Bernice first and then going to the university. The total distance from home to the university if Ashley goes directly is 15 3/4 miles. The total distance if Ashley drops off Bernice first is 9 1/8 miles + 12 1/3 miles = 21 7/24 miles. Therefore, Ashley needs to travel 21 7/24 - 15 3/4 = 5 31/24 miles more if she drops off Bernice.
