### hi.po good day.paano po

hi.po good day.paano po naging 9.47s sa time? thank you in advance po sa sasagot

### 9.47 was found by quadratic

9.47 was found by quadratic formula, I believe you get that, I think what you mean is, why use 9.47 and not 2.54 sec for t. Using 2.54 sec for t is invalid because the second ball was shot 4 seconds after the first ball.
