ok
we had two significant figures as the least in our given
so what i did was to calculate the speed of the airplane...
my result is 52.5m/s... i round it to two significant figures which is 53m/s
but our proff earlier wrote the answer in the blackboard 52.5m/s and considered it as just |V| = 52m/s...
is rounding off in physics different? because I am really certain that .5 can be rounded off to one ... and besides i checked it here http://www.gomath.com/algebra/round.php and its really 53
