Answer:

462 ft/s  

Step-by-step explanation:

The height of the bullet is modeled by:

h(t) = -16t² + 925t------------------------------------ (1)

The speed of the bullet is modeled by the first derivative of equation (1)

dh/dt= -32t + 925------------------------------------ (2)

At maximum height,  dh/dt = 0

0 = -32t  + 925

32t = 925

  t  =   925/32

     =   28.91 seconds

This means that the total time to reach maximum height is 28.91 seconds

Substituting into equation (1) we can calculate the maximum  height:

h = -16 (28.91)² +925 (28.91)

  =   -13,372.61 + 26,742.675

  =  13,367.065 ‬ft

Average speed =  Total distance/ Total time

                         =    13,367.065/28.91

                         =  462.368

                         ≈ 462 ft/s
