Answer:
1.5 seconds
Step-by-step explanation:
plug 0 in for y
0=-16t^2+36
then slove for t
-36=-16t^2
-36 / -16 = 9/4
9/4=t^2
square root of 9/4 is 3/2 or 1.5
t=1.5
Let x = time they take working together . Then:-
1/5 + 1/6 = 1/x
Multiply through by 30x:-
6x + 5x = 30
11x = 30
x = 30/11 = 2.73
answer is 2.73 hours to nearest hundredth
