About thirty seven seconds.
This is an age of ambition and confidence.
And how is that misunderstanding being fixed? Those maps aren't going to make themselves, they need knowledge that can only be obtained by going out and sailing.
At the time the assumption (actually closer to correct than not) was that there was a very big gulf distance wise between europe and asia, a massive ocean (no knowledge of the americas of course). It was columbus who insisted and miscalculated himself the gap was much shorter to get to asia.
The belief was that such a trip would be too time consuming and no crew or vessel would have the resources to mount such a voyage. Which is why it took columbus so long to finally convince someone to fund it. Had columbus not misculated and went with the general idea that the distance was huge such a voyage could have conceivably been held off for a number of decades?
