Exercise 4

Jin and Li have offices on the same highway. Not on the actual highway. All their papers would blow away. They both work just off the same roadway, however.

At noon they leave their offices and drive towards a local restaurant where they have a lunch meeting. Jin's office is 40 miles east of the restaurant, while Li's office is only 20 miles east of the restaurant. What, there wasn't a Subway close by?

If Li gets to the restaurant at 12:20 p.m. and Jin gets there at 12:40 p.m., at what time do Li and Jin pass on the road?
