My friend told me i got this wrong, so i decided to come on here, can someone enlighten me?

To find their speeds, you have to make them per hour instead of c hours.

You would divide each by their times, so and

Train A's speed turns out to be 80 mph and Train B's is 88 mph

train B is faster.

Idk why you got it "wrong," I can't see your work, but I'm pretty sure this is how you'd do it :))
