Tank A is filling up with water at a rate of 5/8 gallon per 1/2 minute. Tank B is filling with water at a rate of 3/5 gallon per 1/4 minute. Which tank is filling faster?

Compute the unit rates.

Tank A:

(5/8 gal) / (1/2 min) = 10/8 gal/min = 5/4 gal/min = 1.25 gal/min

Tank B:

(3/5 gal) / (1/4 min) = 12/5 gal/min = 2.2 gal/min

So tank B is filling faster.

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.
