Has anyone ever had to do the two trains problem?

Has anyone ever really had to do the two trains problem?

For example: A train leaving San Francisco and New York are both headed to St. Louis. The SF train leaves at 7:00 am going 100 miles an hour. The NYC train leaves at 8:30 going 85 miles an hour. Which arrives first?

I’ve never come across this problem in my life in any class I’ve had. I’m not asking how to solve it, I’m asking is it a legitimate problem that would be beneficial to know how to solve to make you better at math? I wouldn’t even know what branch of math would cover this.

Edit: I ask because this is a stereotypical “advanced” (like, high school or late middle school advanced,) math problem that always shows up in cartoons and tv shows. It always seemed unreasonable and unrealistic and sneakily way more complex than it first seems, to have to solve.

Edit 2: I don’t know if I explained myself well because a lot of y’all are not answering what I asked. You’re telling me why math is important. u/DrJaneIPresume is really the only one who answered it correctly.

First go at Birria taco’s. I’m from Wales, be gentle, our ingredient availability is shite

Made with a homemade chilli sauce (made from dried Guajillo, Pasilla, Ancho & Arbol chillies with garlic, onion, tomatoes and apple cider vinegar), 1Kg brisket, & slow cooked in oven for 4hrs @ 140 C. Served with lime, cheddar, fresh Corriander, & raw white onion.

ETA: wow really wasn’t expecting this level of engagement, you guys are awesome!!
So this isn’t only my first time making Birria but also first time eating it, and yeah they were really good!!

Some take aways from your advice- yeah I had kind of thought that the sauce had thickened too much, I added around 400ml of stock about half way through the cooking process but it evidently wasn’t enough with the reduction taking place and there wasn’t even enough left for dipping by the end. I’ll make it as more of a broth style for the next batch, as well as sourcing a fattier cut of beef.

The tortillas were flour as I’m not able to source corn tortillas, but I’ve a press and Maseca on order to make my own.

Thanks for all the great advice, I’ll be back soon
