**Reiny**, Tuesday, November 18, 2008 at 10:07pmlet the time traveled by truck A be t hours, then A went 80t km

clearly the time traveled by truck B must be t-4 hours,

Didn't he then go 90(t-4) km

Now I wonder how far each of them went, ...

**bobpursley**, Tuesday, November 18, 2008 at 10:07pmThe distance they travel is the same, and the time is 4 hours different.

DistanceA=80*time

DistanceB=90*(time-4)

set them equal, and solve for time. That is the total time, if you want the time B was traveling, subtract four hours.
