Consider instead of the original question that the superhero travels linearly until the point in time at which the two trains collide. Then the distance that the superhero travels is dependent only on the final tIme t.

We have that the trains move at the same velocity; meaning that they will meet after traveling equal distances. Thus 2v=2x/t implies that t=x/v. Inputting, t=15/16 hours.

Hence the superhero travels a total distance x=120×15/16=30×15/4=450/4 miles=112.5 miles
