Imagine the following hypothetical situation. An airplane flies in a straight line from point A to point
B and then flies back in a straight line from point B to point A. The airplane maintains a constant
engine speed for the entire flight and there is no wind.
At the same constant engine speed
, would the travel time for the round trip increase, decrease,
or stay the same if instead there was a constant wind that blew from A to B the entire time? Note that
is not the same as the total speed
of the airplane which is a combination
of engine speed and wind speed etc.
Do you have a suggestion
for this puzzle (e.g. something that should
be mentioned/clarified in the question or solution, bug, typo, etc.)?
