**drwls**, Saturday, October 27, 2007 at 12:02pmThe distance between them increases at a rate of 5 miles per hour.

Using that relative rate r,

r t = 5 t = 30

t = 6 hours

**Reiny**, Saturday, October 27, 2007 at 12:43pmYou don't have to know that, you know they are 30 miles apart.

So if you let the time be t hours, then the faster has traveled 45t miles, and the slower has traveled 40 t miles

The difference in the distance traveled is 30 miles, so....

45t - 40t = 30

5t=30

notice we now have the same equation that drwls obtained by simple common sense.
