The answer is: 3840.48 meters.
Explanation
The summit of mt Humphreys point in Arizona is 12600 ft.
Suppose, the summit of mt Humphreys point in meters is [tex]x[/tex]
We know that, 1 foot = 0.3048 meters
So, according to the ratio of 'feet' to 'meter', the equation will be.....
[tex]\frac{1}{0.3048}= \frac{12600}{x}\\ \\ x= 0.3048*12600= 3840.48[/tex]
Thus, the summit of mt Humphreys point in Arizona is 3840.48 meters.
