you are working on a project for school. the project will take 12 hours to finish in all. so far, you have worked on the project for 5 hours and 15 minutes. how much longer you have to finish?

6 hours and 45 minutes

Step-by-step explanation:

First, convert 12 hours into minutes.

12*60=720

Convert 5 hours to minutes and add 15

5*60=300+15=315

Subtract 720 from 315.

720-315=405

Convert into hours and minutes.

405/60=6.75

0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
