enough, most people incorretly answer that the
boat moves less than 1 meter.
The truth is the boat moves MORE than 1
meter. I know, the answer seems paradoxical
and counter-intuitive! But the visual geometric
proof below will help you to understand why this
to “triangle inequality theorem” that
states that for any triangle, the sum of the lengths
of any two sides must be greater than to the length
of the remaining side, we have:
QO < QQ’ + Q’O
QP + PO < QQ’ + Q’O
PO = Q’O
1 m = QP < QQ’
