Speed of the slower truck is x and distance in 6 hours is 6x

Speed of the faster truck is 2x and distance in 6 hours is 12x

12x-6x=204

6x=204

x=34

The slower truck is traveling at 34 mph for 204 miles in 6 hours

The faster truck is traveling twice at 68 mph for 408 miles in 6 hours

The difference of this two miles is 204 miles
