Word problems chap3 -Check your skillls-Relative rates p.56

by nickiss20002000 Fri May 08, 2015 12:41 pm

I do not understand these two problems at all. I tried to use the RT=D chart and was confused about how to set up the equations I needed to solve for.
I read the solutions, but got more confused.
First on Problem # 3,
-What does exactly are we being ask for? I was not sure what I was looking for.
- Why do we add + 1 to Adrienne's time?

Second on Problem 4
-The solution states that is a chase problem, so why not just subtract the rates of both Nick and Cristina and focusing on how quick the gaps between them reduces? Then add this time to Nick's. The set up of the table was confusing because I did not understand what each variables represent.

Just confused about these two problems, and not sure how to approach these types of questions.

Never Mind, after a good night of sleep,I took a look again at these two problems. I finally understood them and know how to deal with these types of questions now :-)
Thanks!
