Question

Two flares are launched from a life raft. The height h of the first flare in metres above the sea is modelled by the formula h1= t2+t+1meters,and the second flare is h2=4-t where t is the time
12 in seconds after the flare is launched. Determine
(i) Time taken and
(ii) Height when the two flares meet each other.
Hint: When two flares meet each other, their heights are the same (h1=h2).
Vinny, I count 6 consecutive posts by you of rather diverse problems, some requiring knowledge of physics.
I did the first one for you.

You have shown no work or indication that you have tried these, and it looks like just a "homework dump". Where do your difficulties arise ?
