A stone is launched off a building which is 95 feet high. Its height at time t is given by the function h(t) = 95 + 10t − 4t2 where time is measured in seconds and height is measured in feet. At what time does the stone reach its maximum height?
A)	t = 1.25 seconds	
B)	t = 2.5 seconds	
C)	t = 5.0 seconds	
D)	t = 7.5 seconds
