It all depends on the direction that each train travels after leaving, and it also depends on what time each one leaves.
Light travels at a constant speed of 299,792,458 meters per second in a vacuum. However, as light travels through different mediums, it slows down depending on the medium. The crazy thing about light though, is that if it leaves a medium and starts travelling back through a vacuum, it once again goes 299,792,458 meters per second.
Plot distance vertical axis and time on horizontal and draw a graph with the first train leaving at zero time plot distance travelled in 4 hours I.E. 300miles draw a line. For second train start from 2 hours on time line and plot distance travelled in 4 hours I.E. 500 and draw line where they intercept draw a line to distance scale horizontally answer 375miles from the station.
The usual trick to this puzzle is that the cabin is at the North Pole.

As blood leaves the heart it travels through the arteries. The first one will be either the pulmonary artery (for blood leaving the right side of the heart) or the aorta (for blood leaving the left side of the heart).
