* On ''Series/MyNameIsEarl'', in the [[BottleEpisode Creative Writing episode]], Joy tells Dodge and Earl Jr. a story to get them to behave themselves and stop whining about having to do homework and pick up their toys. In it, she makes Earl ("Old Daddy") fumble through one of these problems, while (unbeknownst to him) the Crab Shack turns into a desert with train tracks. He gets it wrong, and gets run over by a train, to the kids' horror. Joy explains that ''that's'' why she makes them do their homework.

* An anecdote about mathematician John von Neumann has him presented with a variation on this problem: "Two trains start 100 kilometers apart. They head toward each other at 50 kilometers per hour. Meanwhile, a bee flies back and forth between them at 75 kilometers per hour. How far does the bee travel before they collide?" Immediately, von Neumann answered "75 kilometers". The questioner is surprised that he got the answer so quickly, and remarks that most mathematicians solve it by summing an infinite series (representing each stage of the bee's flight) instead of noticing the easy solution (the trains will collide in one hour; therefore the bee flies for one hour; therefore its total flight is 75 kilometers). Von Neumann replied that he ''did'' solve it by summing the infinite series.

* One ''WesternAnimation/DCNation Shazam'' short has Billy Batson getting this problem at school. Ultimately, he solves the problem by using ComicBook/Shazam's powers to set the trains in motion and see the result. He gets a check minus for not showing his work, however.

* In ''WesternAnimation/HomeAdventuresWithTipAndOh'' episode "Big Brain Boov", this sort of question is an extra credit on Tip's math homework. Unfortunately, a typo ("''why'' is the train?" instead of "where") causes a LogicBomb in the literal-minded Boov and nearly causes the collapse of their society.

* In the ''WesternAnimation/SonicBoom'' episode, "[[Recap/SonicBoomS2E11TheEvilDrOrbot The Evil Dr. Orbot]]", the first question on the test Dr. Eggman takes asks is if a train full of innocent civilians is travelling west at 60 miles per hour and a missile of unspeakable destruction is zooming east at 116 miles per hour, what time the two vehicles will crash and burn. Because Eggman spends so much time trying to answer that one question correctly, he ends up failing the test.

* The problem is poked fun at with a non-train variant in ''Film/SkyHigh'' as something of a FunnyBackgroundEvent. Will is having a quiet, introspective moment while his friends are in the background doing homework.

* One "Bradley the Big Ol' Baby" sketch from ''Series/AllThat'' provides the most exaggerated use of this trope;
-->'''Miss Fingerly:''' If a train leaves Japan at 9:22 [[ItsPronouncedTroPAY AMM]], heading northeast at 300 MMMPH, and a submarine leaves Nebraska at 8:30 PMM, flying eastwest at 3,000 MMMPH, what time will the two vehicles crash and burn?
