. A basketball player is 623

feet tall. His infant son is 14
as tall. How tall is his son?

To find out how tall the basketball player's son is, we need to subtract his height from his father's height.

Height of the basketball player: 623 feet
Height of the son: 14 feet

Now, let's calculate the son's height:

Son's height = Basketball player's height - Son's height
Son's height = 623 feet - 14 feet

Calculating the subtraction:

Son's height = 609 feet

Therefore, the son is 609 feet tall.

The son is 14 times shorter than the basketball player, so he is 623/14 = <<623/14=44.5>>44.5 feet tall. Answer: \boxed{44.5}.
