18/4 = 4 1/2 hours

okay i got that. but now when does sue overtake tony? does sue overtake it in 2hrs less than tom....
BUT HOW FAR DID THEY TRAVEL?

math  Ms. Sue, Sunday, March 1, 2009 at 3:03pm
Here's how I attacked this problem.
When Sue started out at 7:30 she had traveled 0 km and had 18 km to go.
By 7:30, Tom had traveled 8 km and had 10 km to go.
At 8:30, Sue had traveled 12 km.
At 8:30, Tom had also traveled 12 km.
