can anyone tell me how long it takes from london kingscross to stanstead airport and the quickest way getting there please.

Train! Look on the national rail website for times. I would say it takes about 1 hour from Kings Cross. It is easy once to get to Stansted. A well laid out and easy to use airport, more than I can say for Kings Cross station.

is that from kingscross train station to stanstead airport.??????????????
