The 102nd floor of the sears Tower in Chicago is the highest occupied floor. It is 1,431 feet above the ground.How ma ny yards a

Nostrana [21]

The 102nd floor of Sears tower is 477 yards above the ground.

Step-by-step explanation:

We have to convert the height of 102nd floor of the Sears tower into yards. There are 3 inches in one yard. As the feet is smaller unit and yards is larger. When we have to go from a smaller unit to a larger unit, division is used.

So,

3 feet = 1 yard

1431 feet in yards will be:

$=\frac{1431}{3}\\=477\ yards$

The 102nd floor of Sears tower is 477 yards above the ground.
