I scored: Woohoo I don’t need to be press-ganged onto a transport vessel and deported 700,000 miles across the sea
That doesn’t even work if we switch to kilometers (which are significantly shorter than Miles). So, I’m guessing Geography, Navigation, and Astrogation were not on this quiz? (Fun Fact: Even 450,000 kilometers would be well beyond the orbit of the Moon. 2nd Fun Fact: The farthest any human has ever been from Earth is 400,171 kilometers.)
It’s called a hyperbole, more commonly known as over exaggeration. It’s a most interesting aspect of the English language often used in comedy. You should try it sometime.
