If you’re traveling 80 miles per hour, how long does it take you to go 80 miles?
That’s the relatively simple math question Travis Chambers posed to wife Chelsea on a road trip from Logan, Utah, to Boise, Idaho, to visit her family while his camera was rolling.
Her husband posted the video on YouTube, titling it, “The real meaning of MPH,” where her muddled math has unexpectedly racked up more than 3.5 million views.
“I don’t know. Because if I run the mile in like 9 minutes, then, I mean but that’s when I’m out of shape,” she says in the video. “When I’m really in shape it’s like 7 minutes … and that takes me a mile. And we’re going 80 miles. And I’m running 10 mph, if that.”
Using her own running speed as a basis, and taking into account the tire speed, weight of the car, and whether it’s a stick or an automatic, she uses roundabout logic to come up with an educated guess.
“It’s got to take like 58 minutes or something,” she says, not too far off from the correct answer of 60 minutes.
