I was wondering what formulas and approach to use on the problem I submitted in the image I've attached and if my approach has been correct so far

Written Challenge Problem, 1D Kinematics:
A hot air balloon has just lifted off and is rising at a constant rate of 2.0 m/s. Suddenly one of the
passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight
upward with an initial speed of 12 m/s. If the passenger is 2.5 m above her friend when the camera is
tossed, how high is she above her friend when the camera reaches her?
1) Draw a pictorial representation of the problem.
2) Choose a coordinate system. Remember to identify where the origin is.
3) Sketch out qualitative graphs of position as a function of time, and velocity as a function of time
for both the balloon, and the camera. (Try putting graphs for the same variable, but for different
objects, on the same time axis.)
4) List the variables given, variables needed, and any simplifying assumptions being made.
5) Write out the general kinematic equations you will use to solve the problem.
6) Solve algebraically for the variables you need.
7) Comment briefly on whether your result is reasonably believable. If it is – what sort of result
could be easily identified as not believable for this problem?
