They obviously didn't get the family membership pass.
Let c be the number of children, a be the number of adults
5c+30a=185
c+a=12 =>c=12-a
5(12-a)+30a=185
60-5a+30a=185
25a=125
a=5
c=12-5=7
there are 7 children and 5 adults.

we have

This is a vertical parabola open downward
The vertex represent a maximum
where
h is the height of the bird
t is the amount of time, in seconds, the bird had been in the air
For h=40 ft
substitute in the quadratic equation



The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The bird will take 0.88 seconds to reach a height of 40 feet in the air for the first time
