Two trains start at the same time from the same place and travel in opposite directions. If the speed of one is 6 km/h more than the speed of the other and they are 168 km apart after 30 minutes, what is the speed of each train?
The speed of the slower train is 165 km/h and the speed of the faster train is 171 km/h.
Simplify. Assume non-zero denominators.
