Last year the winner of the 50-meter swim finished the race in 27.609 seconds. this year winners completed the 50-meter swim in 0.032 fewer seconds. how long did it take this year to swim 50 meters?

Well it is not at all difficult to solve this question as we have to subtract the time from the previous swimmers time.

So to calculate the time for this years winner we should be knowing the time for the previous years winner too which is given to us and is 27.609 seconds. As this time the swimmer was 0.032 seconds quicker we will subtract this value from 27.609 seconds.

So the answer is 27.609 - 0.032 = 27.577 is this years 50 m swimmers time.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
