A student needs to get to class on time. His sibling's school starts at 7:50. The student's school starts at 7:45. It takes the parent approximately 8 minutes to drive to the sibling's school and takes 16 minutes to drive to student's school. The siblings cannot be at the school any earlier than 7:35 and the student cannot be at the school any earlier than 7:30.

Make a plan for the parent to drive where first so that everyone is on time and so the student can be a little early so he can go to his locker to get ready for his first period class.

Kinda long, I know. :P

Leave house at 7:20. Go to students school (16 minutes) arrive at 7:36. Then go to siblings school (8 minutes) arrive at 7:44

Sorry, I knew left something out.

It takes 15 minutes to go from the students school to the siblings school and the same vice versa. 

So it wouldn't work, sorry. :-(

I'm thinking maybe leave at 7:15, come to students school at 7:30, take siblings to their school which would take 15 minutes and they would arrive there at 7:45. Perfect ^_^
