**Reiny**, Thursday, October 21, 2010 at 9:39pmspeed of slower ---- x mph

speed of faster ---- x+3 mph

after 2 hours:

distance covered by slower = 2x

distance covered by faster = 2(x+3)

solve

2x + 2(x+3) = 206

.

**Reiny**, Thursday, October 21, 2010 at 9:50pmAre you looking at the answers to this question?

There is no need for two variables

I defined x to be the slower speed, and x = 50

I defined x+3 to be the faster speed, or x+3 = 53

distance covered by slower in 2 hours = 2(50) = 100 miles

distance covered by faster in 2 hours = 2(53) = 106

and what is 100+106 ? ...

looks good to me.
