A bullet is shot straight upward with an initial speed of 925 ft/s. The height of the bullet after e seconds is modeled by the fun h(t) = -1662 - 9250
where h is measured in feet. Use the function h to find the average speed of the bullet during the given time intervals.
(a) The first 6 seconds
ft/s
(b) The first 40 seconds
ft/s
(C) Between t = 10 and t = 40
ft/s
