"Hey, Ricky. A jet plane leaves Las Vegas
at ten o'clock a.m. It's destination is New York City.
It's traveling one thousand miles per hour."

"On the same day, a single engine prop plane leaves New York City
at ten o'clock a.m. It's destination is Las Vegas.
It's traveling five hundred miles per hour."

"Which plane is closest to New York City
when they meet?"

Ricky.
"Oh, that's easy. The jet plane."

Tricky.
"Nope. When they meet
They're both the same distance
from New York City."
