Answer:
4.016\ hr

Explanation:

Given

Train A has speed of
v_a=75\ mph

Train B has speed of
v_b=50\ mph

If Paris and Pisa is 500 miles apart

If they meet x hours after the start

The sum of the distances traveled by Train A and B is 500 miles


\Rightarrow 75* x+50* x=500\\\Rightarrow 125x=500\\\Rightarrow x=4.016\ hr

So, after
4.016\ hr they will pass each other.
