Question 613552: 2 postmen leave at the same time from cities A and B, respectively, & travel toward the other city. The speed at which they travel is constant but different from each other. After they meet each other one needs 16 more hours to reach his distination, & the other needs 9 hours. How long did they travel before they passed each other?
t- time traveled before meeting
AC=V1t
BC=V2t
CB=16V1
CA=9V2 Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! AC=V1t
BC=V2t
CB=16V1
CA=9V2
AB=BA=a
BC=CB=b
using different variables
a=st;
b=vt;
b=16s;
a=9v
solve for t
t=a/s
t=b/v
a=9/v
