## Homework Statement

Elaine leaves at 5:55 AM and averages 66 mi/h. Newman departs Chicago heading for Dallas at the same time Kramer leaves at a speed of 75 mi/h.

c. At what time does Jerry pass Newman?

d. What percentage of the trip has Elaine completed at the time Newman has completed 70% of his trip?

## Homework Equations

I have no idea, sorry, other than the speed equation maybe that I already used. I have no idea how to answer those questions although I know it should be easy.

## The Attempt at a Solution

I know they end up at their destinations at these times:

Newman: 6:58 PM

Kramer: 7:39 PM

Jerry: 9:39 PM

Elaine: 9:04 PM
