Question 170334: HELP! I am completely stuck on this problem:
A twin-engined air craft can fly 1200 miles from city A to city B in 5 hours with the wind and make the return trip in 8 hours against the wind. what is the speed of the wind?
I have solved so many of these before in geometry, but that was over a year ago, and I can't remember how to solve it.
When I attempted to figure it out, I was not sure if the equation with the wind was 5+X and if the one against the wind was 8-X, or x-8.
Thanks so much for the help! it really means a lot!

Question 170619: Jeff leaves his house on his bicycle at 8:30 am, and averages 5 mph. At 9:00 am his wife leaves, following the same path and averages 6 mph. At what time will joan catch up with Jeff?
t= time jeff travels
using the equation d=r*t, I get 5t=6(t-1/2)
expanding- 5t=6t-3
-t=-3.
So my question is, am I solving this right? And if so, what is t=3? Does that mean she will catch up to him in 3 hrs? the only other way I could imagine it is that it means she will catch him at 3 oclock but that doesn't seem right.
thank you!
