Quandaries and Queries JJ Student Secondary Level Questions   I don't really understand the directions of this problem: A student who commutes 27 mi. to college remembers, after driving a few minutes, he forgot a term paper. Driving faster than usual, he returns home, gets the paper, and once again starts to school. Sketch the graph of the student's distance from home as a function of time. Does it mean that the student drives at normal speed,  drives faster to pick up the paper, and resumes normal speed to head back, or that the student drives at normal speed, then drives faster the rest of the way to college? Thanx Hi JJ, I agree, it's not clear. Since he to make up time I would assume that he drives faster for the remainder of the trip after he remembers the term paper. In your solution to the problem you should say this, he drives at his normal speed until he realizes what he forgotten and then faster for the remainder of the trip, both back home and then off to college again.
