JohnnyWayne,
We know that Rate*Time=Distance.
We know that west bound distance + east bound distance = 250 miles.
We, also, know that they traveled for the same amount of time because Chicago is on Central time and Detroit is on Eastern time.
So, if Rw is rate westbound and Re is rate eastbound, then (Rw*T)+(Re*T)=250.
Which is the same as T(Rw+Re)=250.
Filling in rates is T(90+50)=250 or 140T=250.
Isolate the T by dividing both sides by 140 gives T=1.79 hours.
Rw*1.79 = 160.71 miles West of Detroit.
Which is conveniently close to Three Rivers Archery Supply!
Sorry, school has started and I had to practice so that I would be ready when the kids start asking.
What I am wondering is, did Terry make that Ghilli hat? If so, how did he make it? I thought he had green and tan dreadlocks for a long time until I saw a picture of him without it on!
