Victor Vauxhall set off in his Vauxhall Victor to drive from Vauxhall to Victoria in London. He drove at a constant velocity of 30mph. There was no other traffic on the roads at that time, however he never reached his destination. Why?
I'm going to guess that
Since he was going at a constant velocity [which means both constant magnitude and direction ] he inevitably crashed into something as he tried to turn (which he can't really do).
Here is a picture of what probably happened
velocity is speed and direction, a constant velocity means straight-line motion. That would put Victor in the Thames river.
He will not be reaching Victoria today.
Okay, I've got a few jokey answers here, and I'm not sure about any of them, which is why this is probably good for a lateral-thinking tag.
Guess 1: (Original guess which is best suited to the lateral-thinking tag)
His destination wasn't Victoria in London?
Other, slightly more jokey guesses:
Looking at a map, you have to cross the Thames to get there; maybe he crashed into the river because this is the first obstacle he'd hit if he travelled at a constant speed and direction?
The Vauxhall Victor was last produced in 1978, so Victor is dead now?
PS: As a science geek I really appreciate Joe-You-Know's answer, because that was my original Guess 2! Go upvote his answer!!
He ran out of fuel, his car stopped and that's why he never reached Victoria.
