Boat or plane ? Depends on tide or wind speed/direction. Measured against what reference too, earth's rotation.

Are you factoring in the 20 minutes when you sit shamefaced in the back of a police car pretending that you had no idea how fast you were really going in a 40mph zone?

Are you factoring in the deceleration from the 2,700,000 mph we are travelling through space?

ok, if you went at 100mph for the first half hour, how fast would you need to go for the second half hour to average 80

8 more MPH and it would take minus thirty years.

Conveyor belts? Where we're going we won't need conveyor belts.

60mph obvs*. Is this like those competitions on the tellybox designed I presume to entice stupid people into thinking that they are the only ones who know the answer to questions like this?

* Assuming immediate deceleration from 100 to 60...

It'd have to be a road bike surely..? You couldn't maintain speed on a MTB.

Viz

Drivers - avoid being nicked by the new average speed cameras by doing 90mph for 2 minutes then stopping for a spliff

I'm trying to think of a clever answer, but what would happen if you sampled the speed every mile rather than every minute?

The tyre turning thing obviously affects it.

Assuming mph is miles per hour not metres per hour - the defintion of (constant) 80mph is travelling 80 miles in an hour. So how can the answer not be one hour? What am I missing?

Or is this an oblique reference to Zeno's dichotomy paradox?

If I go 80mph for one hour, how far have I gone? ** Mind Blown **

how far have I gone?

depends what route you take - it your on the M25 you'll be 37 miles away from where you started (and in quite a bit of trouble when you open the post in a few days time)

if its around the circumference of a 25 mile wide circle you'll have gone nowhere ...fast.

But you've stil gone 80 miles.

but how then do you measure the distance between two places?

Indeed - you'd be smarter to go the other way round - you'd get there in less than half the time

Indeed. You're mixing a linear geometry (nearly flat plane) with a non-linear one (the road network). So you get these apparent paradoxes.

Yes. The journey was 80 miles. And we were travelling at 80 mph. And it took us 61 minutes as we stopped for 1 minute to buy some sweets.

If I was to go out tomorrow and drive eighty miles at eighty miles an hour for the first time in my life it will have taken me over fifty-two years.

It depends whether you are doing 80mph or just think you are doing 80mph.

Your car speedo registers a higher speed than you are actually doing - you can easily compare this when you have your sat nav on - the speed on there is usually different...

The difference can be up to about 10%.

What if they measure the miles 10% shorter to compensate though. Have you thought about that?

1 hour as the crow flies, but "to go 80 miles" is a little bit ambiguous

Surely that depends how fast the crow is flying though?

And are we talking airspeed or groundspeed?

Was the car fueled up on the right side or was the hose stretched over the car? This, as we all know, has a huge impact on everything including how fast you travel.

That was quick! Oh, I know, you're one of those who parks right by the shop doorway despite the double yellow lines...

Amusingly that video spawned a whole host of similar ones with similar disrespect.

This guy has it pretty much down to an art:

time.

Before rail travel it used to be a 24 hour journey from London to Bristol.

It's now a 24 hour journey from London to Sydney.

Bristol used to be as remote from London as Sydney is now.
