How long would it take for an object to hit the ground from 1248 ft tall building?

In a vacuum, just under 9 seconds. In the real world, more than
that, but it depends on the shape of the object and the prevailing
winds and air currents.

To answer this question we need to know if you are multiplying, adding, subtracting, or dividing. If you are adding it would be 94. For multiplying it would be 1248. If subtracting it would be negative 62.
