Damian Hutchinson · Answer 1

The train crossed the bridge 2h after leaving the station.

Areli Roach · Answer 2

The x intercept is where the line crosses the y axis or where D (h) = 0

D (h) is the distance that the train is from the station

so that means that when D (h) = 0, that is when the train is at the station
