Answer: 316 ft
Explanation:
So, you want to find out the hight differences.
You take the height of the Trump International Hotel and Tower (we will refer to this as "a") and you take the height of the Chrystler Building (we will refer to this as "b"). You find the bigger number (a) (a=1,362 ft) and you subtract it from the smaller number (b) (b=1,046 ft).
So this looks like:
a-b
(1,362-1,046)
Which is 316 ft
I hope this helps.
