Why is an estimate not a guess?

A guess is less accurate than an estimate. If someone were to ask how long ot would take to drive car from the East cost of America to the West coast you might guess 3 days - based on your "gut" feel with no data to support your answer. A estimate would take more time you might follow these steps:

It is about 3000 km coast to coast. At 100 km/he that would take 30 hours of driving. But you can't drive for more than 10 hours a day, so that is more like 30x24/10 = 72 hours. Then you can't go 100 km/hr all the way what with back roads and towns and mountains so add another 30 hours or so that's almost 100 hours. Your estimate would be 4 days.

The estimate might not be absolutely correct, it is however defensible.
